Jimmy McNulty:
It would need to be introduced as either a stand alone policy or as part of the wider Health & Safety policy.

There would need to be justification (for example after an accident, smelling of drink) or if its random selection the company would need to be able to prove that it truly is random selection.

Your contract would already reference that you agree to abide by the company policies

^^^^^^^^^^^^^^^^^^^^^^^
truly random is fair enough i would think in a large faceless company.
in tesco as you go out the gate,theres a button for you to whack,if it goes red,you go in for a quick pat down search by a cabbage.
its totally random and no biggy to me personally.
