Mate, come on you know damn well that's too darn easy...:lol:

Thought I would give a little update on the outcome of the issue.
I put a fatigue policy together to be reviewed and approved by management and in the interim the other company that was employing them let them go due to H&S risk.
Still waiting on the policy to be approved and implemented so we do not end up in this situation again, which with the cost of living feels a bit inevitable.
To those that suggested a pay rise might help, you are right it really would, but not within my control.
Thanks for all the advice and suggestions.
