In my experience, Google doesn't offer 80% time. I switched to 80% time at Google (and 80% salary/vesting) but that was my suggestion after a number of years. It wasn't straightforward to transition (I think it needed VP approval), but I didn't encounter opposition either. I found that 80% time is a much bigger quality of life benefit than you might expect, since it's a 50% increase in the number of days you have off.
