Klacks schedules front of house, kitchen, and housekeeping under the labour law of the United Arab Emirates — with eight hours of normal working time plus a maximum of two overtime hours (Decree-Law 33/2021, Art. 17, 19), the 48-hour week, and the 50 percent premium for rest-day work (Art. 19, 28).
UAE labour law knows no minimum daily rest between shifts — only a break rule: after no more than five hours of work, at least a one-hour break is due (Art. 18). Scheduling discipline is therefore entirely up to the business.
Hotels in continuous operation may average up to 56 hours per week across shifts — capped at 144 hours over three weeks including overtime (Cabinet Resolution 1/2022, Art. 15). Averaging this correctly over weeks is hardly feasible by hand.
The 50 percent premium for overtime between 10 p.m. and 4 a.m. expressly does not apply to shift workers (Art. 19(3)) — anyone who doesn't separate this cleanly in the schedule pays too much or too little.
Klacks is installed on your own infrastructure — via Docker; allow about half an hour for the first start.
Public holidays and rest periods come preconfigured for your country, surcharges where defined for your country — and you can adjust them anytime.
Klacks builds shift plans, flags conflicts and optimizes routes — with an AI assistant if you want.
From the early shift to the night shift — it all works together.
Klacks monitors the daily maximum of eight hours plus up to two overtime hours and the 48-hour week (Art. 17, 19) — every breach is flagged immediately.
One day off per week is mandatory (Art. 21). Anyone working on the rest day receives a compensatory rest day or a 50 percent premium (Art. 19(4), 28(2)) — Klacks keeps track of both.
Klacks credits overtime, night, and rest-day premiums automatically as time credits — including the shift-worker exception for the night premium, configurable per rule set; the hours are ready for your payroll.
At most two rest days in a row may be worked through (Art. 19(5)) — Klacks flags overlong work stretches before they end up in the schedule.
“Schedule the weekend, two servers are out sick” is enough — Klacksy starts the replanning.
If someone drops out, Klacks immediately shows who's qualified, available, and within the configured maximum-working-time limits.

In the United Arab Emirates, all official public holidays are decreed centrally by the UAE Cabinet — uniformly for all seven emirates, with no cantonal or municipal variation like in Europe. The real challenge lies elsewhere: holidays whose exact date is only confirmed at short notice, and businesses that plan across several Gulf states.

Klacks offers countless ways to calculate rules and hour credits for nights, weekends, public holidays and overtime — exactly the way your contracts and company agreements require.
Klacks flags time collisions, rest periods that are too short, too many consecutive working days and work on holidays right as you plan — as an error or warning in the error list.
