What makes a good PM employer? Besides pay.

I currently work for a company that is known to not be flexible with employee work styles. To not bog y'all down with all the details, but a big one is that we're not just PMs - we're technical trainers, workflow consultants, software testers, and above. I think the stress from my job certainly comes from doing the work of what I have seen at other companies be at least 3 different jobs.

But there are other characteristics that I've read are just common across all PM jobs. The stress of people taking their frustrations out on your as the project face, working with factors that you can't completely control like 3rd-parties, yada yada.

For those who have been PM'ing for your careers, what things do your employers do that makes the work tolerable? Besides pay.
