1) If you have the six months of emergency funds saved up that you are supposed to, and are either single or married without children, I'd probably quit. Assuming you have actual technical skills I'd move that up to should probably quit.
2) If you have three months or less of emergency funds and/or have children and/or you or someone in your family has a chronic medical condition I would grin and bear it in public, and network furiously to try and find another job so that you aren't "cutting off your nose to spite your face"
3) In both of the prior cases I'm taking it as a given that you are at best ambivalent about your current position or employer. If it's a job you love and it is just the situation that is a problem, then talking with your boss to help explain why it is a problem may be worthwhile. As hard as it may be to believe, some folks out there may look at the setup and not see it as a problem. Either because they're not doing it, or they actually like the ride time to do other things.
Hope this helps...
