Variable part-time: notification and schedule retention
Plan specific framework in work rules and communicate each schedule in advance. Simple mention of 'flexible schedules' is not sufficient.
The writing indicates fixed weekly duration or average duration with its reference period, as well as the variable character of the schedule. The rules set possible days, time ranges, minimum and maximum durations and notification procedures.
Notify a written, dated and individual notice at least seven working days in advance. A mandatory collective agreement may shorten this period, in principle to a minimum of three working days; verify sector exceptions noted by SPF.
Keep the notice where the rules are viewable during its application, then for one year. Record deviations from schedules. Bases: article 11bis of the July 3, 1978 law and articles 157, 159 and 160 to 169 of the December 22, 1989 law-program. The general schedule framework allowed since June 2026 does not replace this specific framework.
