>>> One could say, yes, ok, I took that trade-off, but now I got to be a dad, and that's worth more to me. That's it ! More precisely : I've chosen to be dad for reasons which are absolutely not rational. Therefore, the question of the trade off is not that important. >>> You should not lose that much yep, that's what I'm aiming for. Thing is, the way you put it, I understood that "business suffers from those people who choose to be parents". For me parents are like taxes : as a business, that is as a member of the society, you abide to respect the rules : you pay your taxes because the society decided it's positive for everybody, ditto for parents. But I think we agree :-) >>> I think you might underestimate the amount your employer has invested in you. >>> How much would it cost him to replace you Not much : maybe waiting a year to find an ideal candidate (so I'd say a month of work), and then a year to train the guy (say, 6 months). So basically 7 months of salary. not much. Hint : I don't work in hyper hitech stuff, I just run very big, long lived applications; nothing fancy.
