Although probably somewhat different from "standby", as known in aviation, this decision may set an interesting precedent inasmuch as this tribunal has determined that hours spent on standby is time which the employees must recognise as duty.
As such, why should not the same responsibilities apply regardless of where that work is performed, eg. meal allowances?
Perhaps more interestingly, is the employee covered by the same employer insurance, when one is at home, on standby? In theory, I guess (from a layman's point of view) that it should (apply).
Nice little can of worms here!
