Staff planning in cleaning: sites, travel time and short shifts

Published on 23 October 2026

A cleaning company doesn't schedule departments, it schedules sites. Fifteen teams, thirty addresses, shifts of one to four hours, early in the morning or late in the evening, and a client who calls on Friday to say the offices need an extra clean twice a week starting Monday. Try to control that with one Excel tab per month and you lose time to the same puzzle every single week.

This guide sets out the scheduling rules that apply specifically in cleaning and building services: the minimum duration of a shift, travel time between sites, the publication of part-time work schedules, and the administration attached to all of it.

Why cleaning schedules are structurally harder

In most sectors you schedule people at one location, within one opening window. In cleaning, three complications stack up:

Scattered workplaces. One cleaner does two offices in the morning and a third in the evening. The schedule determines not only who works, but also in what order and with which journey in between.
Short shifts. Many contracts sit well below a full-time week. A 1.5-hour site is normal, and those hours have to be combined economically.
High turnover and lots of replacements. Sickness on a six-hour morning site isn't solved with "we'll push it back". The client expects the place to be cleaned.

The result: planners rebuild the same structure every week. Yet 70 to 80 percent of a cleaning schedule is repetitive — fixed sites, fixed frequencies, fixed time windows. Only the exceptions deserve real attention.

The minimum shift duration: 3 hours, except in cleaning

The Belgian Labour Act lays down as a general rule that every work shift must last at least three hours. If you let someone work for less, you still have to pay three hours. There are exceptions to that threshold, including via royal decree and sectoral collective agreements (more detail from FPS Employment).

Joint committee 121 (cleaning) is one such exception. In the sector guidance for blue-collar workers, the minimum shift is set at one hour, which may be spread across several directly consecutive sites. The average weekly working time in the sector is 37 hours.

That "directly consecutive" is crucial for your planning. You can't simply scatter single hours across the day and then act as if each site counts separately. The logic is: a series of sites that follow on from one another together form a single shift.

What that means in practice for your schedule:

A one-hour block standing on its own, with hours of gap before and after, is vulnerable both operationally and legally.
A block of 1 hour + 1.5 hours + 1 hour that joins up (including travel) is exactly what the exception was designed for.
Always check your own joint committee and company-level agreement: a facility management business may fall under a different joint committee than classic cleaning.

Travel time between sites: not neutral

The time a cleaner needs to get from site A to site B is a classic point of discussion in the sector. The sectoral agreements provide for compensation of the time needed to travel from one site to another, and there are procedures for disputes about imbalances between travel time and actual working time on site.

The rule of thumb to build into your planning: commuting to the first site and home from the last site is something different from travel between sites during the shift. The latter counts as time your employee gives to your business — and therefore towards your wage cost.

What that means for a realistic schedule:

Build in explicit travel blocks, not invisible slack. Someone combining offices in two municipalities needs 20 minutes, not 5.
Build site combinations geographically, not alphabetically or per client. One team covering three addresses within the same radius costs less than two teams criss-crossing town.
Measure afterwards. If actual time structurally deviates from your plan, you're paying extra every week without seeing it. A time tracking system that records start and stop times per site makes that gap visible immediately.

Part-time work schedules: fixing and publishing them

Most cleaning contracts are part-time. That brings obligations that have nothing to do with the sector itself:

The work schedule must be fixed — in the work rules for fixed schedules, or through publication for variable schedules.
With variable part-time schedules, the employee must be notified in advance, within the period set out in the work rules (subject to a statutory minimum notice period).
You must be able to show which schedule applied at which moment. In an inspection, what counts is not what you intended, but what you can produce.

The minimum thresholds for part-time working hours have been relaxed in recent years; we cover that separately in part-time contracts: from the 1/3 rule to the 1/10 rule. And if you want to change a schedule that has already been published, first read changing a work schedule: what Belgian law says.

Planning replacements before you need them

In cleaning, the absence question isn't "whether", but "which site today". Start making calls at 5:30 am and you either lose the site or pay for an expensive emergency fix.

Three measures that work straight away:

Backup per site cluster, not per person. For each geographical zone, designate two or three employees who know the sites in that zone (keys, badge, product instructions). That way you're not searching your entire workforce.
Keep availability digital. Who wants extra hours? Who can't start before 9 am? Who has no car? That information belongs in your HR administration, not in the team leader's head.
Log replacements. A replacement you don't record comes back later as a discussion about pay, travel allowance or overtime.

From planning to administration: one chain

Every scheduling decision in cleaning drags administration along with it. An extra pair of hands for three evenings means a contract, a Dimona declaration and correctly recorded hours. If you use flexi-job or student workers for peak moments, additional specific rules apply — see flexible work.

The gain lies in not retyping anything. When the schedule, the time records and the payroll and contract administration share the same source data, the classic source of errors disappears: a schedule that was changed but never passed on to whoever prepares the payroll.

Checklist for your cleaning schedule

Do you know the minimum shift rules of your joint committee, and does your schedule respect the condition of directly consecutive sites?
Is travel between sites visible in the schedule, with realistic durations?
Are your site combinations built geographically?
Are all part-time work schedules correctly recorded and published on time?
Do you have at least two backups per zone who already know the site?
Are actual hours recorded per site, so you can compare plan and reality?
Do Dimona and contract flow automatically from the same schedule?

Get these seven points in order and you don't just schedule more compliantly, but more cheaply too: most hidden costs in cleaning sit not in hourly wages, but in badly combined sites and hours that were never recorded properly.
