Keep the 5-day workweek, but make the standard vacation day allocation 25-30 days instead of 10-15. I still don't understand how you are supposed to allocate 10 measly vacation days over an entire year. Take a week-long vacation in the summer and you only have 5 stupid days left! Taking off the day after Christmas (where nobody does any work whatsoever) brings that down to 4. Sure, if you work for a company 10 years you start getting some real vacation time, but let me see a show of hands of software developers who stay at the same company for 10+ years!
