Is there any regulation of uptime and rest times for ground personnel accompanying aircraft?

The rules on flight time limitations and rest periods, as set out in Subpart ORO.FTL, apply to flight and cabin crew members. In addition, in cases of carriage of cargo in the passenger cabin, it is also required to be applied to cargo surveillance personnel in flight.

However, there is no specific similar legislation applicable to land workers, the labour regulations and collective agreements being applicable.
