In France, the way employees can make up for lost working hours is determined by specific rules that depend on whether the absence was personal or due to a collective work stoppage. For personal absences, there is no automatic right to reclaim the time not worked. Employees cannot simply take time off for personal reasons and then later reclaim those hours. Any absence must be approved and categorized as a paid holiday, unpaid leave, or another legally recognized type of absence. If the absence is paid, the time not worked is not reclaimable and is valued based on the hours that would have been worked had the employee been present. For unpaid absences, agreements between the employer and employee, such as temporary schedule changes, may be possible, but these must not violate labor laws regarding weekly hours, daily rest, or overtime compensation. When it comes to collective work interruptions—such as those caused by accidents, bad weather, force majeure, inventory checks, or short-term layoffs—the Labor Code allows for the possibility of reclaiming lost hours, but only under specific conditions. However, a holiday layoff does not qualify for reclaiming lost hours. In 2024, the Court of Appeal in Nîmes ruled that requiring employees to reclaim unperformed services on holidays was illegal, as it violated the Labor Code. Collective agreements or sector-specific agreements can define how lost hours are reclaimed, and any such arrangements must be reported to the labor inspector. Employers are not allowed to terminate employees for lack of activity in the month following a reclaim period, unless the employee was temporarily hired for an unusual increase in workload. Compensatory rest for overtime hours is a separate process from reclaiming lost hours. If an employee works more than the legally allowed weekly hours, they are entitled to either a salary increase or equivalent compensatory rest. Collective agreements may allow for overtime pay to be replaced by compensatory rest, but the weekly counting principle must be strictly followed. The Court of Cassation has clarified that overtime hours must be tracked on a weekly basis, and informal compensation across weeks or months is not valid unless there is a proper working time adjustment system in place. The formal procedures for reclaiming lost hours vary depending on the situation. For collectively lost hours, the deadline for reclaiming depends on the applicable collective agreement, with limits on daily and weekly overtime hours. For mandatory compensatory rest, employees can request it as soon as they have accrued seven hours of rest, and they must take it within two months. Employers have seven days to respond to such requests, and if the rest is deferred, the employer must propose another date within the applicable period. Employers must ensure that employees take their rest within a year of it being accrued, and if the employment ends before this time, the employee must be compensated for the acquired rights. Proper documentation is essential for all reclaim processes. Records should include the nature of the absence or rest, the date and duration, the source of the hours, the number of hours to be reclaimed, whether the absence was paid or unpaid, the date the hours will be performed or the rest will be taken, and the counting method. Employers must create documents that track working hours and compensatory rests, especially when schedules differ among employees. Daily tracking, weekly summaries, and monthly records of overtime hours and compensatory rests are required. Employers who fail to follow these rules risk salary recalls or disciplinary actions for exceeding working hour limits or failing to provide required rest. Employees who take unauthorized or repeated absences may face salary deductions, disciplinary action, or even dismissal. Both employers and employees must ensure that all procedures are followed, agreements are checked, working time limits are respected, and accurate records are maintained to avoid disputes.
