I would have no hesitation in puitting down fatigue if I felt unfit for work because of it.
The LAW states that a controller should not work if he/she considers him/herself unfit forduty.
One sniff of being hauled in to the office would :
a) Bring my Union Rep immediately in to action
b) Have me considering legal action against the "manager" concerned.
It's about time people (ie "managers") realised that ATCOs are a PROFESSIONAL body of workers and NOT "skivers".
The trouble is, within this whole industry, that the staff are not treated as professionals by their "management".....it's always been the problem, and always will be the problem (especially within NATS)
