Peuce exactly.........
Be very carfeul people doing extra shifts, remember its up to you on your days off whether you are fit or not? If you have an incident, and or accident (lets pray to god we dont) dont think an excuse "well I was fatigued" wil cover you? Before you know it, it will be your fault that YOU went in on your day off, you had the choice to weigh up your fatigue, but you measured it as sufficient? Sufficient to what? Reasonable OT? I dont think so................
