The office and the operation clear at different times
In most warehouse premises the administration staff finish before the operation does. The office empties in the late afternoon while picking, loading and despatch continue for some hours afterwards, and the amenities used by warehouse staff remain in use throughout. Treating the whole premises as clearing at one time will place the attendance wrong for at least one part of it.
The workable structure is a sequence that follows the departures. The front office and any meeting or reception space are serviced once the administration team has left, and the amenities, crib room and any operational office are taken after the shift finishes. That produces one attendance with an internal order rather than two separate visits in most premises.
