Go over the manager's head. If that company is having trouble keeping senior staff, there are reasons for it and those reasons are probably not secret. I've done this, with mixed success, but have never had a problem with retaliation. You might be surprised how welcome your skip-level feedback is. Oh, and if your skip-level manager doesn't know who you are (and ideally, his manager), then you either need to work on visibility, or you're not as senior or as pivotal as you might think. Be polite. Tell them that you thought flexible hours were part of the deal. And then walk. Moving to a new team in the same company is probably just as good, if you can swing it.
