Well, I'm not arguing, but I just don't see asking people to talk to the employees as being management PR.
It's easy to talk about "oppressors" and the like, but it's a shame to hurt those who can least afford it in order to live in some marxist dream world.
It seems like a reasonable request to me, to talk to the employees there (you don't have to buy anything). If it is management PR, then they must feel that they've been treating their employees in a decent manner. At any rate, it does seem reasonable. It's so easy to look at the world through pre-concieved dogmas, but in fact, the world is a little more nuanced then that (sometimes), and it couldn't hurt. And like the first poster jokingly suggested, maybe there's no one you can trust on these sites: it could be "evil management" pr, or it could be "evil union" pr.
The thing to do is just go in and talk to the employees yourself (again, you don't have to buy anything).
I did, in fact, and I won't go in detail, but the situation there does seem a little more nuanced than: bad management, good union.
