Klacks schedules front of house, kitchen, and housekeeping in Ireland — with split shifts, Sunday and public-holiday premiums, and statutory rest periods, with Klacks warning when they are not met. The planning helps absorb seasonal peaks and absences.
Lunch and dinner service with a break in between: split shifts are the norm in Ireland's hotels, pubs, and restaurants — and they raise rest-period and premium questions that are nearly impossible to plan cleanly by hand.
Seasonal peaks, temporary staff, and changing availability: the staffing mix shifts weekly, yet the schedule still has to be right.
Business peaks exactly when everyone else is off — reconciling premiums, rest periods, and Sundays off is the real art of scheduling.
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 schedules lunch and dinner blocks and checks minimum rest periods and daily maximum hours in the process — every shortfall is flagged immediately.
Statutory rest-period limits that you set up are monitored in real time — violations are flagged immediately. On request, Klacks blocks them in block mode in the automatic planning paths (e.g. wizard, suggestions, substitution); in manual planning, Klacks warns.
Klacks credits night, Sunday, and public-holiday premiums as time credits in hours — configurable per country and rule set, as an hours basis for your payroll preparation.
Shifts are only filled by staff with the right qualification — Klacks warns about expiring certifications before they become a problem.
“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 rest-period and maximum-working-time limits.

The Republic of Ireland has no public holidays at county or municipal level: all statutory holidays apply uniformly nationwide under the Organisation of Working Time Act 1997. For businesses with ties to Northern Ireland, though, what applies across the border still matters — a completely separate holiday regime is in force there.

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.
