Not sure what you mean by "abusive place to work". I know a couple people who work for, or have worked for, Microsoft in various capacities, but so I have some insight into what it is like there.
My college roomate worked for them for a number of years out at the Redmond home office as a developer. This was back in the 90's, so things might have changed. He said that although the workload was sometimes heavy, especially near the time of a release, most of their policies were very developer friendly.
Every developer had their own office, even the junior level ones. That way, you don't have the distractions that you would get in a standard cube farm. You could pretty much set your own hours, including working at home if you wanted to. My friend was a night owl, so he would go into the office around noon, stay till five, leave for a few hours to eat and recreate, and then he might go back to the office around 9 or 10 and work past midnight. Not many places give you that type of freedom. If you needed some piece of hardware or software, you got it. My friend had like 4 or 5 PC's in his office to test the software on various versions of Windows. He even had a Mac (!) to test the Mac version.
As far as work environment goes, MS bent over backwards to keep people happy. The department had a "morale" budget that was used for outings to the movies, to set up a LAN for gaming, and other stuff that the team wanted. And of course you had your free beverages and snacks available to you. Not to mention, the Redmond campus is just gorgeous. It had the feel of a college campus with its expansive greens and pristine buildings. There were even folks taking a break playing ultimate frisbee on one of the lawns. And of course, you got all of the usual benefits: health care, 401(k), employee discounts on software. Then there are those stock options that everyone talks about. Back in the 90's when the stock was on the rise, those options were worth more than your salary in some cases.
That's not to say that everything was all wine and roses there. As I mentioned he did work some long hours at times because there is a lot of pressure to "ship" products. However, I never heard of him refer to anything there as being abusive. He was well compensated for his hard work, and he had a lot of freedom and a lot of fun there, too.
