Labour Shortages: How to Keep Costs Down

Labour shortages are costing you 15% of your profit—here’s how to stop it bleeding further

Say your average weekly payroll is £12,000, and you’re losing 10% of shifts to no-shows, sickness or staff leaving. That’s £1,200 a week, or £62,400 a year, just in unfilled hours. Add in the cost of hiring replacements—recruitment ads, agency fees, training new staff—and you’re looking at another £15,000 to £20,000. That’s not a one-off; it’s a recurring hit to your bottom line every time you’re short-staffed.

The usual fixes—raising wages, offering bonuses, or cross-training—help, but they don’t solve the root problem: you’re paying for labour you can’t reliably use. The real cost isn’t just the money spent; it’s the lost sales when service slows, the wasted food when the kitchen’s overwhelmed, and the customers who never come back after a bad experience. A single understaffed shift can cost you £500 to £1,000 in lost revenue, not to mention the damage to your reputation.

The answer isn’t to slash hours or cut corners—it’s to reduce the financial pain of shortages by making your existing team work smarter, not harder. That means three things: cutting the time wasted on admin, streamlining the workflow so fewer staff can handle the same rush, and ensuring every hour you do pay is spent on revenue, not fire-fighting.

Here’s how to do it without breaking the bank or your staff’s morale.

The hidden costs of labour shortages

You know the obvious costs: fewer hands mean slower service, longer queues, and tables sitting empty. But the real money leaks happen in the gaps—places where understaffing turns into lost profit you don’t even notice.

1. Wasted food and ingredients

When the kitchen’s overwhelmed, staff rush orders, over-portion, or throw out food that sits too long. A busy Friday night with three fewer cooks than planned? You might bin £80 to £120 in unused ingredients—food that’s already cost you 30% of its sale price to buy. Multiply that by four weeks, and you’ve lost £320 to £480 on waste alone, before you factor in the customers who leave because their meal was cold.

2. Lost sales from slow service

Every minute a table sits empty is money left on the table. If you’re turning tables every 45 minutes instead of 30, you’re losing 33% of your potential seatings per hour. At £25 average spend per table, that’s £250 an hour, or £2,000 over an eight-hour shift.

3. Staff burnout and turnover

When you’re constantly short-staffed, your existing team picks up the slack—until they don’t. Burnout leads to higher turnover, and every time you lose a cook or server, you’re looking at £500 to £1,000 in recruitment and training costs per hire. If you’re replacing two staff a year, that’s £1,000 to £2,000 you could’ve kept in your pocket.

4. Delivery and marketplace losses

If you rely on delivery or marketplaces, understaffing hits you twice. First, riders can’t keep up with demand, so you lose orders to competitors. Second, the platforms penalise you for slow fulfilment, pushing your orders down the search results. A 10% drop in visibility on a marketplace can mean 15% fewer orders—and that’s before the commission cuts in.

The fix isn’t to hire more people. It’s to make the people you’ve got work faster, smarter, and with fewer headaches.

How to cut labour costs by 10% without firing anyone

You’re not going to eliminate shortages overnight, but you can reduce the financial damage by shaving 10% off your labour costs—not by cutting hours, but by cutting waste. Here’s where to start:

1. Automate the admin that’s eating your staff’s time

Servers and cooks spend 15 to 20 minutes a shift on tasks that don’t earn you money: writing receipts, reconciling tabs, chasing down missing orders, or manually entering tips. That’s £12 to £18 an hour—more than a junior staff member earns—just on paperwork.

How to fix it:

• Table management: Use a system that auto-sends receipts, splits bills instantly, and flags slow tables so staff can upsell without running back and forth. A server who spends 10 minutes less per table on admin can take two more tables an hour—that’s £50 to £75 extra revenue per shift.
• Kitchen workflows: Digital tickets cut the time cooks spend deciphering handwritten orders. A kitchen display that updates in real time means no more “I didn’t see that” excuses—and fewer rushed, wrong orders.
• Inventory tracking: If your staff are manually logging stock, you’re wasting two hours a week (or £15 to £25) on a task that should take 30 minutes. Automate it, and free up that time for floor work.

Cost: The Starter plan starts at £90 a month. If it saves you two hours of labour a week, it pays for itself in three weeks.

2. Streamline the kitchen to handle rushes with fewer cooks

A well-run kitchen can serve 20% more orders with the same staff by cutting down on wasted motion. The key is standardising every step so cooks don’t have to think—just execute.

How to fix it:

• Prep stations: If your cooks are running back and forth between the grill, fryer, and prep table, you’re losing £50 to £80 an hour in efficiency. Dedicate zones for prep, cooking, and plating, and train staff to stick to them.
• Batch cooking: For high-demand items (burgers, pizzas, pasta), prep components in advance. A burger station with pre-formed patties, sliced onions, and pre-toasted buns can halve the time per order during rushes.
• Digital menus: If your menu’s a handwritten list taped to the wall, cooks waste five minutes per order figuring out what’s what. A digital menu with photos, modifiers, and prep notes cuts that to 30 seconds—saving £20 to £30 an hour in a busy shift.

Cost: A kitchen display system like Berryin’s starts at £90 a month. If it reduces order times by 20%, you’ll recoup the cost in one slow week.

3. Turn your staff into a well-oiled machine

The biggest waste in a restaurant isn’t idle hands—it’s idle brains. If your team isn’t trained to work as a unit, you’re leaving £100 to £200 a shift on the table.

How to fix it:

• Cross-training: A server who can also take orders at the bar or help in the kitchen covers three roles instead of two. That’s one fewer body you need to hire—saving £15,000 to £20,000 a year in recruitment.
• Shift huddles: Spend five minutes at the start of every shift running through the day’s specials, slow items, and table turnover goals. A well-briefed team serves 15% more tables per hour than a disorganised one.
• Incentivise speed without sacrificing quality: Offer a £5 bonus per shift to the team that turns the most tables without dropping below a 90% customer satisfaction score. Track it with a quick post-meal survey or a comment card system.

Cost: Zero upfront. The only investment is your time—30 minutes a week to train and brief your team.

The trade-offs: what breaks when you cut labour costs

You’re not just saving money—you’re shifting it from one part of your business to another. Here’s where the risks lie, and how to avoid them.

1. Service slows down (but not as much as you think)

Risk: If you cut staff hours to save money, queues get longer, and customers leave.

Reality: You’re not reducing staff—you’re reducing wasted time. A server who spends less time on admin can take more tables. A kitchen that’s organised can handle the same rush with one fewer cook.

How to measure it: Track your average table turnover time for a week before and after changes. If it stays the same or improves, you’re winning. If it drops by more than 5%, you’ve cut too deep.

2. Staff morale drops (but only if you do it wrong)

Risk: If you automate tasks or change workflows without consulting your team, they’ll feel undervalued—and quit.

Reality: Staff hate repetitive admin. A server who spends less time chasing down missing orders and more time with customers? They’ll stay longer and work harder.

How to sell it: Involve your team in the changes. Ask, “What’s the one thing that wastes your time every shift?” Then fix it. If you roll out a new system without their input, you’ll get pushback. If you make it their idea, they’ll own it.

3. Food costs creep up (but you can stop it)

Risk: If cooks are rushed, they over-portion or waste ingredients. That cuts into your margins.

Reality: A standardised portion guide—with photos and weights—cuts waste by 10%. Train your cooks to use it, and you’ll save £500 to £1,000 a month on food alone.

How to track it: Weigh your waste bins for a week. If food waste drops by even 5%, you’ve made back the cost of the system in one month.

What happens when you don’t fix labour shortages

Let’s say you do nothing. Here’s what your P&L looks like in six months:

Problem	Cost per Month	Cost per Year	Cumulative Impact
Unfilled shifts (10%)	£1,200	£14,400	£86,400 over 6 years
Recruitment & training	£1,500	£18,000	£108,000 over 6 years
Lost sales (slow service)	£2,000	£24,000	£144,000 over 6 years
Food waste	£800	£9,600	£57,600 over 6 years
Total	£5,500	£66,000	£400,000 over 6 years

That’s £400,000 you could’ve kept—just from doing nothing. And that’s before you factor in the customers you lose forever.

The 80/20 rule: where to focus first

You don’t have time to fix everything at once. Start with the two changes that give you the biggest bang for your buck:

1. Automate table management and billing. This alone can add £50 to £75 per server per shift—just by cutting down on admin. See how Berryin’s system works.
2. Standardise kitchen workflows. A digital menu and prep stations can reduce order times by 20%, meaning you need one fewer cook per rush.

These two fixes pay for themselves in weeks, not months. Everything else is icing.
