I watched this John Oliver[0] a few days ago which shows that apparently (I am not from the US and also have never had to deal with unions) it does not matter anyway illegal or not.
Is it not true? That it is illegal to fire but that the repercussions are almost nothing for the company?
I see they are trying to make far harsher laws against this in some articles but for now it seems a mess no?
If you want to understand laws of _other_ countries you would have understand lot more laws and precedents for those laws.
Anything you "learn" from drive by political skit is garbage.
It is a comedy show, but it's not there to educate you on these subjects. It is there to pique your intrest, and to inform you that an alternate way of looking at the subject exists, and you should go learn more about it.
Edit: re: "investigations"
This isn't investigative reporting. You could have put the information in this segment together sans comedian from your laptop with probably 20 minutes of googling. It's all well known facts that are out there that he's bringing to the surface.
