When I was a manager of a small team, I use to say: "I'll be the last to leave and I want to leave early". That's was usually enough to magically make programmers to leave earlier and still get thinks done, because working late has to do a lot more with bad habits than with technical problems. And no, they didn't work from home, they couldn't (it was a very restrictive environment). Sure, sometimes they had some tough problems, and I usually stayed in my own office only appearing to ask them if they wanted something to eat, for example. I also use to have a brief meeting after two hours or so just to evaluate if it still made any sense to stay or it was better to leave and come back early when other involved people were around (for example, a DB expert).
