Yeah, if you're not offering me 75% pay for 50% work I'm not interested. My peak productivity is 3 days a week. The gains from working more than that are marginal at best.
Do you get 75% pay for 50% work? Based on no particular experience, it seems that would be difficult to sell.
I get paid considerably more than 75% for 50% _time_. [1] Mainly because I'm in a position where I get paid by the value of my work rather than by the amount of time I waste behind a computer monitor.
[1] My bad. I should have said time instead of work.
