Klacks treats the annual summer midday ban (June 15 to September 15, daily from 12:00 to 15:00) as a blocked period — Klacks flags assignments within it immediately, and on request automatic planning does not place any shifts there.
Note on the sample data: All names, places (for example Winterthur), addresses and figures in these recordings are fictitious demo data with a Swiss background, written in Latin script. They only illustrate the product – you do not need to know or be able to read them. In your own installation you enter your own data, and the interface is multilingual.
From June 15 to September 15, all work under direct sun exposure is banned daily between 12:00 and 15:00 (حظر العمل تحت أشعة الشمس) — violations are reported via hotline 19911.
The schedule must mandatorily provide for split assignments during this window — tedious to coordinate by hand across many sites and teams.
A Saudi employee counts as a full unit (1.0) toward the Saudization quota only if the GOSI-insured salary is at least SAR 4,000 per month — critical for facility management firms.
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 blocked periods to route planning — it all fits together.
Klacks sequences sites so that travel distances stay short.
If the 12:00 to 15:00 window from June 15 to September 15 is stored as a blocked period, Klacks flags assignments within it immediately, and on request automatic planning does not place any shifts there. You create the split shifts before and after it yourself.
Changing crews and absences: Klacks keeps track and suggests suitable assignments.
Klacks calculates neither salaries nor Nitaqat classification — whether the GOSI salary threshold for the full quota unit (1.0 from SAR 4,000) is reached is checked by your payroll system; Klacks provides the hours worked as a file export.
Specialised cleaning, machinery, security zones: only appropriately qualified staff are assigned.
"Schedule the sites for tomorrow morning, before the midday ban" is enough — Klacksy starts the planning, Klacks optimises route and team.

In Saudi Arabia, the Ministry of Human Resources and Social Development decrees all four official public holidays centrally — uniformly across the whole Kingdom, with no provincial or municipal level like in Europe. The real challenge lies elsewhere: the two religious holidays, whose exact date is only confirmed at short notice by moon sighting.

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.
