I can believe how incompetent G4S are, and a lot of other large companies. They now run on two principles
Profit:
Job Protection:
The upshot is that they will only recruit people who won't argue (no matter how stupid the policy/instruction) at the minimum possible wage.
Guess what? These recruits cannot cope with a crisis or, even if they could, aren't going to speak up.
Expect things to get worse.
