What is the average hours for working week in the US, UK is 37 - 40 for manufacturing.
What Manufacturing we have left the work week can be up to 50 hrs i would guess, 40hr regular time and the rest is over time.
Well, this is all incidental, I have no statistics, but
typically we work a 40 hour week, Managers and salaried employees often stay much longer, Many companies are trying ergo-friendly shifts like 4 12 hour days.
Here in the States a blue collar worker gets his 40 hours and hopes for 10 more in overtime. (usually 1.5x's hourly rate) 70 hour weeks are not uncommon.
