Taking away cell phones is standard practice at all sorts of companies. At ExxonMobil, I technically wasn't allowed to have a phone with a camera in it, which, when I went to get a new phone, would basically have been I can't have a phone. I just didn't make a big deal about it and, you know, didn't steal any company property, but incoming guests would probably have to dump theirs in a bowl.
Breaks in the break room for a working factory floor isn't entirely unreasonable either. The work area is for working and the break area is for breaking. Which makes it sound like they should hold battle dancing competitions in there, but I imagine that also has to be a firing offense.
The medical leave stuff is a little weird - I would have thought that it would violate the FMLA.
The problem, though, is that there are still hella people who want these jobs. These terrible jobs are better than the alternative in that part of Ohio, apparently. This isn't a sign that unions need to exist - all that would happen if the employees formed a union is that the company would go hire some of the thousands of other people who would rather have a shitty job than no job at all. What it is a sign of is that the economics of existing in that particular part of the world right now are terrible, and it might be an indication that it would be a pretty good place to start sending government aid, if we were Franklin Roosevelt. Though, given the fact that this is Ohio that we're talking about, I kind of wonder if they'd take it, based on their general performance in the Republican primaries every year.
