Skill Thinning in Restaurants: How to Stop the Drift Before It Reaches the Plate

You can usually spot skill thinning long before anyone gives it a name.

• General manager who has never truly learned the host stand.
• Line cook trying to recreate a signature dish after watching it demonstrated once
• Executive chef who earned the title after only a fraction of what their predecessor accumulated.

Individually, those situations feel familiar. Together, they point to something bigger.

For Deirdre Auld, CEO and partner of Boston-based Coda Restaurant Group, they are evidence of a structural shift quietly reshaping restaurant operations. She calls it skill thinning: the gradual erosion of hard-earned experience across every layer of the business.

It is not a catchy phrase or a criticism of today's workforce. It is a practical way to describe what happens when experienced people leave faster than new ones can develop, and when a business begins relying on knowledge that exists mostly in people's heads.

That perspective comes from an unusual career path.

Before leading Coda's collection of restaurants (SRV, Baleia, Gufo, The Salty Pig, and the soon-to-open Celine), Auld stepped away from hospitality altogether. She earned a master's in organizational development, became a certified executive coach through Northwestern, and spent years studying how people actually learn, develop expertise, and build lasting competence.

On the meez Podcast episode with Josh Sharkey, she laid out why that gap is widening and what leaders can do about it.

When she returned to restaurants, she saw the industry differently

The challenge was not simply hiring. It was preserving knowledge in an environment where people were gaining fewer repetitions, moving into leadership faster, and inheriting responsibilities that once took years to earn.

"The adage 10,000 hours to mastery has existed for a long time for a reason, because you need repetition, you need practice, you need to be exposed to things that are challenging."

That observation reframes an issue many operators instinctively treat as a staffing problem. Auld argues it is something else entirely. It is a knowledge problem.

When experience becomes thinner across the organization, standards can no longer depend on the handful of people who happen to remember them. The standard itself has to become something the business can preserve, teach, and repeat, regardless of who is working the shift.

Skill Thinning Is About Systems, Not Generations

One reason Auld's idea resonates is that it avoids an easy trap. She is not interested in blaming younger workers or claiming people do not work as hard as they used to. In fact, she pushes against that narrative.

Skill thinning, in her view, is the product of larger forces that changed how people enter, learn, and advance in the industry. Two shifts stand out.

The first was COVID. Restaurants lost experienced employees across every department. Businesses promoted promising people earlier than they normally would have, not because they were fully ready, but because they had little choice. The talent pipeline thinned almost overnight.

The second shift is cultural. Information has become compressed. Tutorials arrive in short clips, advice comes in bite-sized posts, and learning feels immediate because the information is immediately available.

But access is not the same thing as mastery.

Watching someone explain a technique is not the same as performing it repeatedly under pressure, adjusting when something goes wrong, or understanding why a process exists in the first place. Surface knowledge creates confidence quickly. Deep knowledge takes repetition. And restaurants are built on repetition.

The demographic picture reinforces why this is not temporary.

According to Modern Restaurant Management, roughly 4.1 million workers are expected to retire annually between last year and 2027, while fewer younger workers enter the labor force to replace them. The people carrying decades of operational knowledge are leaving faster than the industry can rebuild that experience.

Skill thinning is what happens when experience exits faster than a business can rebuild it.

Why the Middle Matters More Than Most Operators Realize

Every restaurant depends on a layer of people who rarely get much attention: the sous chefs, the floor managers, the assistant general managers, the shift leaders.

They are rarely the public face of the business. But they are responsible for something more important than executing today's service. They are where tomorrow's leaders learn how to lead.

Historically, these roles gave people time to accumulate reps before stepping into executive chef or general manager positions. They learned finance by helping manage costs. They handled difficult guests before owning the dining room. They developed judgment one shift at a time.

COVID disrupted that progression. As experienced managers left, restaurants promoted people faster than ever. Auld does not see that as a failure of ambition or talent. She sees it as a consequence of circumstance.

Being underprepared

The result is people stepping into general manager and executive chef roles with far less runway than the industry historically expected.

Auld described GMs who do not yet have a real handle on finances, on reservations and the books, or on navigating a genuinely difficult guest, not because they lack talent, but because they have not yet had the time. The modern restaurant GM role already demands financial literacy, systems thinking, and people management at once, and skill thinning asks people to do all of it sooner.

That middle layer is not a nice-to-have. It is where standards move from leadership into everyday execution: where recipes become habits, culture becomes routine, and expectations become consistent. When it thins, those standards have fewer chances to be reinforced before they reach the front line.

Eventually, inconsistency reaches the guest.

The turnover numbers make it harder still. Toast data reported by NRN puts the average annual restaurant turnover rate at 78 percent, meaning restaurants are constantly onboarding new employees while experienced ones move on.

“Every new hire is another transfer of knowledge, and another chance for standards to drift if they are not documented somewhere beyond the memories of veterans.”

Skill thinning rarely arrives as a dramatic event. It happens quietly. One promotion. One departure. One shortcut. One undocumented process at a time.

The Real Cost Shows Up on the Plate and the P&L

Because it creeps in through small inconsistencies, skill thinning is an operational issue before it is a staffing one. A sauce tastes slightly different on Tuesday than it did on Saturday. A portion runs a little heavier on one station. A guest complaint that would once have been handled instinctively escalates because the manager has simply never encountered it before.

None of those moments feels catastrophic alone. Together, they erode consistency, the thing guests notice most even when they cannot explain why.

The financial impact follows quickly.

Research from Black Box Intelligence, cited by FSR magazine, puts the cost of replacing a single manager between $10,518 and $16,770, with hourly replacement running around $2,305.

Every time someone leaves, a restaurant loses more than a person. It loses accumulated judgment and the countless small decisions that person no longer had to think about. When replacements are promoted before building those same instincts, the cycle repeats.

But the first place operators feel it is not payroll. It is the food. As meez explored in this blog on restaurant employee turnover, under-trained teams are more likely to over-portion, misfire dishes, and create waste. This drives up food cost percentage and drives down guest satisfaction at the same time.

That is what makes skill thinning so hard to diagnose. It does not look like one problem. It looks like dozens of small ones.

Documentation Does Not Replace Experience. It Preserves It.

If experience is becoming scarcer, where should that knowledge live?

For Auld, the answer is straightforward. Not in someone's memory. Not in verbal walkthroughs. Not in hoping the opening chef trains every new hire exactly the same way. It has to live in the system.

Her background in organizational development pushed her toward reflection, communication, and clarity as leadership fundamentals, and the operational version of that clarity is documentation, not as bureaucracy, but as a way of protecting standards when people inevitably come and go.

The industry data backs the instinct. One 2026 training trend flagged by Modern Restaurant Management argues that YouTube-style learning does not drive confidence and mastery, and that operators have to close the gap between theory and reality with real learning tools.

Watching a clip is not the same as being able to do the thing under pressure. Documentation bridges that gap. It gives people something stable to return to after the demonstration ends.

Recipe data becomes the training layer

A documented recipe does not just preserve ingredients and measurements. It preserves decisions, captures technique, and records intent. And unlike verbal instruction, it does not become less accurate because someone took a vacation or accepted another job.

In meez's blog on what Julia Child understood about recipe training, when a recipe changes it either pushes instantly to every station with visual steps intact, or it travels by email thread and printed cards and relies on hope.

The first is a system. The second is skill thinning waiting to happen.

Strong documentation creates consistency in ways verbal training never can. It means:

• Every cook trains against the same standard, regardless of who is leading the shift
• Recipe updates reach every location immediately instead of spreading informally
• New hires learn from documented best practices rather than one person's habits
• Institutional knowledge stays inside the business even when experienced employees leave

That matters most as restaurants scale. Without documented systems, every new location is another chance for standards to drift. With them, every location starts from the same foundation.

Turning recipes into digital training materials with photos and video is how you give a week-one cook access to a decade of reps they never personally lived through.

It is also how restaurant training leaders make new hires train to a standard rather than to whoever happens to be on the schedule. Technology does not replace experienced people. It protects what experienced people already learned.

AI Can Thin Skills Too, Unless You Stay the Last Mile

Auld is notably balanced on AI. She is not skeptical of the technology itself. She uses it daily and credits it with giving independent operators access to resources that once required much larger organizations.

But she also sees a subtler risk. Not that AI will replace people. That people will stop exercising the judgment AI cannot replace.

"AI is sometimes thinning skills. It is giving us outputs back that allow us to skip the critical thinking or the challenge piece around it."

The danger is not using AI. The danger is accepting its output without engaging with it.

Auld describes watching people generate documents or plans with AI and immediately copy and paste the results without reading closely, questioning assumptions, or asking whether the recommendation actually fits the situation. That is where learning begins to disappear.

Critical thinking is not replaced overnight. It slowly weakens through lack of use.

Sharkey's counter is that the human has to stay the last mile: use the tool for leverage, but never outsource the judgment. It is the same logic that applies to a recipe system. The technology should carry the standard and the repetition, so the human can spend their scarce reps on the things software cannot do.

A chatbot cannot calm an angry guest, read the mood of a dining room, or coach a struggling cook through a rough shift. That skill, Auld noted, cannot be prompted. A server at an upset table cannot glance at a chatbot for the words.

Curiosity Is How the Standard Actually Sticks

Documentation solves one problem. It does not solve them all.

A recipe system can tell someone what to do. It cannot make them care enough to keep getting better. That is where Auld's coaching background shapes her leadership. She believes genuine learning begins with curiosity, not compliance.

One story from her own team shows the difference.

While preparing for the Montreal-inspired opening, Auld traveled with members of her leadership team, including an incoming general manager who excelled with guests and staff but had never developed much interest in wine. The traditional approaches had not worked: training modules, online courses, encouragement. None of it sparked much enthusiasm.

Then, over three days and roughly 700 dinners, that general manager watched Auld and the bar director talk about wine with real excitement. The conversations were not lessons. They were expressions of curiosity. Gradually, questions replaced indifference. Interest replaced obligation. Learning happened naturally because someone first became curious enough to ask why.

For Auld, that is the role leadership should play. Documentation carries the standard. Leaders create the curiosity that makes people want to meet it. The two are not competing ideas. They are complementary ones. Systems preserve consistency. People inspire growth.

The recipe system holds the standard so leaders can spend their energy building the curiosity that makes people care about it.

Better Systems Create Better Coaching

One of the most interesting parts of Auld's perspective is what she does not argue. She never suggests documentation replaces leadership. She argues the opposite.

“The more clearly operational standards are documented, the more time leaders have for the work that cannot be documented: coaching, observation, feedback, building judgment.”

Those are the parts of leadership that create future leaders, and they are often crowded out because managers spend their days reteaching recipes, correcting preventable mistakes, and answering questions that should already have standardized answers.

When documentation handles the repetition, coaching becomes intentional. Instead of explaining what to do for the tenth time, leaders can spend their energy on why it matters. As meez has written in its guide to effective kitchen management, documenting standards rather than relying on verbal walkthroughs keeps institutional knowledge from being locked in one person's head, and frees the veteran to actually develop the next one.

That is a much better use of experience. It is also how organizations begin rebuilding the depth skill thinning has eroded.

The Question to Ask Before You Promote

Auld's framework flips the usual reflex. When they are short on experience, operators tend to ask an external question: how do we hire stronger people? Her question is internal: can our standards survive the next handoff?

That is harder, because it has nothing to do with recruiting. It forces operators to examine whether the business depends on a handful of experienced people, or whether the organization itself knows how to teach what they know.

Instead of asking "how do we find more experienced people," operators can ask:

• If our best sous chef left tomorrow, is their knowledge documented, or is it walking out the door?
• Can a week-one hire execute our signature dish to standard without a veteran hovering?
• When a recipe changes, does the new version reach every location instantly, or does it rely on hope?
• Are we spending scarce coaching time on the why, or burning it re-explaining the what?

None of those questions is really about recipes. They are about resilience.

Every promotion, resignation, and new opening gets easier when the organization's knowledge is carried by systems instead of individuals. Documented, visual recipe training is not just an operational exercise. It is succession planning.

Skill thinning is not going to reverse on its own

Auld's own read is cautiously optimistic that tech-industry layoffs may finally send capable, curious people back toward restaurants over the next several years.

But even then, the restaurants that win will not necessarily have the most experienced teams. They will have the strongest systems for turning experience into something everyone can access. Because standards should never depend on whether the right person happens to be on the schedule.

FAQ

What is skill thinning in restaurants?

Skill thinning is the gradual reduction of both technical and leadership experience across a restaurant workforce, a term used by Coda Restaurant Group CEO Deirdre Auld. It describes what happens when experienced employees leave faster than new ones can build the same competence. COVID-era staffing disruptions, accelerated promotions, shrinking attention spans, and overreliance on AI have all contributed to the trend.

Why did restaurant middle management get thinner after COVID?

The pandemic forced a large reduction in force and reshaped who was working and how many. That hollowed out the sous chef and floor manager layer, the roles where people traditionally built reps before running a kitchen or floor. Operators then promoted people into GM and executive chef roles with far less developmental time than before, leaving leaders without a full handle on finances, reservations, or difficult guest situations.

How much does restaurant turnover actually cost?

Restaurants average roughly 78 percent annual turnover, according to Toast data reported by NRN, and every cycle triggers new onboarding and training. Black Box Intelligence research, cited by FSR magazine, puts the cost of replacing a single manager between $10,518 and $16,770, with hourly replacement near $2,305. Beyond the direct cost, each under-trained hire adds a stretch of inconsistency that raises food cost percentage and hurts guest satisfaction.

How do documented standards help with skill thinning?

Documented, visual standards keep the recipe consistent even when the person who set it is not in the building. Instead of relying on someone remembering a technique, teams train to a version-controlled recipe with step-by-step photos and video.

As meez explains in its guide to effective kitchen management, documenting standards rather than relying on verbal walkthroughs keeps institutional knowledge from being locked in one person's head.

Does AI make skill thinning worse?

It can, if people use AI outputs without reviewing them. Deirdre Auld warns that copy-pasting AI results without asking what it said, why, and how it will land erodes the critical-thinking muscle. Used well, AI carries repetition and leverage so people can spend their limited reps on judgment and human connection, the skills software cannot replace, like handling an upset guest in real time.

How can restaurants train new staff faster when the skill pool is thin?

Turn recipes into the training material. Visual, station-level recipes let a week-one hire execute to standard without a veteran hovering, which is how operators train new staff up to 70 percent faster. meez's staff training approach centralizes onboarding, procedural, and SOP materials in one hub so every location works from the same current standard rather than from whoever is on shift.

Do performance improvement plans actually work?

Auld argues yes, when the leader goes in genuinely trying to develop the person rather than to document an exit. She has seen a sous chef come back from a PIP and later earn a promotion. She treats a PIP like coaching: define the goal, name the deliverables clearly, and give the person an artifact they can reference so nothing feels blindsided. The mindset of the person writing it largely determines the outcome.

Should coaching start before someone becomes a manager?

Auld believes the ideal first moment for coaching is early, when someone is transitioning from individual contributor to leader, before hard habits form. Coaching a C-suite leader can still work, but unwinding years of built-in patterns is roughly double the effort. Building leadership skills before the habits set is easier than breaking them later.
