Because I am currently working ~50 hour weeks to try and deliver two of NATS top 10 projects on time and cost optimised and to my user's satisfaction
Look at your NATS contracted weekly hours ... if they are less than 50, and you are not selling your soul to the overtime devil, then you are a silly person.
If you are doing more than your contract for free, or being rewarded at a stupid rate for anything over your contracted hours, you are a fool to yourself. And screwing it up for all your fellow workers.
