Ramp Night shift workers on airport
can work more than 8 hours. The norm is of them to work 12 hrs.
Exceptions to night working time limits- the job needs round-the-clock staffing (for example, hospital work)
To make long night shifts work (i.e.12 hr shifts) you just need to get your times right to make sure you get you rest periods spot on. e.g. 12hrs rest in a 24hr period. I used to work 19:00 - 07:00 shift.
But the law on rest times can be flexed aswell, there is always a loop hole
