Yes, lots - if you are being serious, and not ironic / sarcastic - perish the thought on pprune.
It is an unequivocal 'assumption' that a well rested pilot is better able to function than one who is not well rested.
If, by conventional rostering protocols you need x number of pilots, and you operate with a number lower than x, then the workforce will have to be rostered harder, affecting the first 'assumption'.
I have no idea whether the company in question has sufficient pilots, as I don't work there. I'm NOT commenting on that - or any other airline, just the maths of any given situation.
The same applies to workers in a nuclear power plant, or any business for that matter.
