The 4-day work week in UK hospitality: a practical guide

**Compressed-hours model:** the same weekly hours over four longer days. A 40-hour-a-week chef moves from 5×8 to 4×10. Pay stays the same; total hours stay the same; only the pattern changes. Cheapest to introduce because labour cost per week is unchanged.

**100-80-100 model:** 80% of the hours, 100% of the pay, 100% of the output. A 40-hour-a-week chef drops to 32 hours over four days. The labour-cost-per-hour rises 25%, and the bet is that productivity rises enough to cover it (fewer mistakes, lower turnover, fewer sick days). This is what the 2022 UK pilot tested.

In hospitality, most operators trialling the model use compressed hours for kitchen and back-of-house, and 100-80-100 only for salaried management roles. Front-of-house typically stays on existing patterns because cover requirements don't shrink just because individual weeks did.

The simplest pattern is **fixed 4-on-3-off**: each worker has the same three rest days every week. Easy to communicate, easy for staff to plan childcare and second jobs around. Works when you have enough headcount to keep every day covered without everyone needing the same days off.

The harder-but-fairer pattern is a **rolling 4-on-3-off rotation**: the four working days shift week-to-week, so weekend days are shared. A 7-week cycle gives each worker the same weekend pattern over time, and stops the new starters always being landed with Fri-Sat-Sun.

A third option is **two-team week-on-week-off**: Team A works Mon-Thu, Team B works Thu-Sun, with Thursday as a handover/training day. Used by some 24/7 pub operators because it pairs naturally with longer shifts.

**The 48-hour weekly limit.** Averaged over 17 weeks. A 4×10 pattern is 40 hours — fine. A 4×12 pattern is 48 — on the limit, with no headroom for overtime. If any week could push past 48, the worker needs a signed opt-out on file.

**Daily rest: 11 consecutive hours in every 24.** A 12-hour shift ending at midnight followed by an 11am start is fine. A 12-hour shift ending at midnight followed by a 9am start is a breach. Build a minimum 11-hour gap into the rota tool.

**Weekly rest: 24 consecutive hours in every 7 days, or 48 in 14.** Four-day patterns make this easy — you have three rest days every week.

**In-shift breaks: 20 minutes for any shift over 6 hours.** A 10- or 12-hour shift legally only requires 20 minutes; in practice most operators run two 30-minute breaks for fatigue and food-safety reasons.

**Under-18s cannot work more than 8 hours a day or 40 a week.** A 4-day week with 10-hour shifts is not legal for under-18 workers without exception.

Statutory holiday is 5.6 weeks. The unit is **weeks**, not days — so a 4-day-week worker is still entitled to 5.6 weeks of holiday, which equals **22.4 days** (5.6 × 4), not 28.

For irregular-hours and part-year workers (most casual hospitality staff), the rolled-up method introduced from 1 April 2024 applies: holiday pay accrues at 12.07% of hours worked in a pay reference period.

If you move existing staff from a 5-day to a 4-day week mid-leave-year, recalculate their outstanding entitlement pro-rata. Don't simply carry over the 28-day figure — staff lose out and you risk an underpayment claim later.

**Cover gaps move, they don't disappear.** If your chef now works Mon-Thu instead of Tue-Sat, Friday-Sunday kitchen cover has to come from somewhere. Most operators end up hiring 10-15% more headcount or moving to a 2-team rotation.

**Shift-swap policy needs an update.** When everyone works 10-hour shifts, a swap is a bigger ask. Tighten swap deadlines (e.g. 48 hours notice) and make swaps approval-only rather than peer-to-peer.

**Overtime becomes more expensive.** A worker on 4×10 who picks up a fifth shift is on day 5 of 5, with weekly hours running 50+. Decide in advance whether the fifth shift is paid at time-and-a-half and document it.

**Forecasting matters more.** A compressed-hours rota has less slack — one no-show on a 4-day pattern is 25% of the worker's week missing, not 20%. Operators who run 4-day-week rotas well are also the ones with the tightest demand forecasts.

**Pilot one team for one quarter.** Kitchen-only or BOH-only is the usual starting point. Don't roll out site-wide on day one.

**Agree the success metrics in advance.** Typical ones: covers served per labour hour, sick days, staff turnover, customer complaint rate. Without baseline numbers you can't tell whether the pilot worked.

**Get opt-out forms signed before the first week.** Anyone whose pattern could hit 48 hours needs a fresh 48-hour opt-out on file — the old one may not be valid if the contract changes.

**Communicate the pattern eight weeks ahead.** People accept a 4-day week far more readily when they can see the cycle in writing and know when their three days off fall.

**Review at week 6 and week 12.** If the metrics aren't moving the right way, the pattern is wrong (or the role isn't suited to it) — don't wait six months to find out.

Compressed-hours 4-day weeks work best where workers control their own pace — kitchens, prep teams, salaried managers, back-office. They work least well in pure front-of-house roles where cover is dictated by service times.

The 100-80-100 model needs genuine productivity gains to break even. In hospitality those gains usually come from lower turnover (you stop paying recruitment and training costs every 4 months) — which means it only works if you commit to it long enough for retention to compound.

If you are not ready for either, a useful halfway step is a guaranteed two-consecutive-days-off rule, which captures most of the rest-and-recovery benefit without changing weekly hours at all.
