"But why are people forced to work 65 h ?"
Because their job warrants it, because that's what it takes to get a promotion in some areas, because they want to, because some employers are bastards and demand more than is capable in 37.5 hours a week... and many more that I can't think of at the moment.
I work part time, having previously been full time in my roll. I do 3 days, I work strictly to my hours (I have to because of childcare arrangements) yet I have to do more work in 3 days than I would expect to working 5. I'm NOT a slacker and work bloody hard, but even I struggle to fit everything in.
DH on the other hand works a 50 hour week, plus random hours on call (which he is obviously paid for). How the frig would you rationalise our working arrangements which suit us financially, are very beneficial to our family and we've worked for years to accomplish.
If some wanker decided that DH could only work 30 hours a week then we wouldn't be able to afford the mortgage, we wouldn't be able to afford to run the one car we have, and I would have to go to work full time, except that would only equal 30 hours a week. Childcare would be a mess and Europe and the US would fucking laugh at us for having such a ridiculous rule.
I don't know why i'm bothering tbh... I should have just said "because it's a fucking stupid idea"
