Yeah you're right generally, but I've made it pretty clear that I'm barely capable of working the hours I'm contractually obliged to, let alone any extras. If you're being a super keen spaz doing 70 hours a week from day one you're just fucking yourself and fucking your comrades, but me doing this 4 hour shift for my boss will deffo be rewarded more than adequately. At the very least I'll get the hours back and if I make any cock ups in the next couple if weeks this will lessen the pain.
