> Many companies would agree if you offered them to work 3 days a week for 60% of your salary. I've done it.

My last employer refused to even accept 4 days a week for 80%. Manager brought up how much the company had invested in training me as a grad (which, to be fair, they did), and that cutting my hours would have meant that investment had gone to waste.

I now work for them 0 days a week. Funny how that works.
