Many unions will offer you cheap insurances covering up to 3 times that amount. And you can actually be in the union and get many benefits even as an entrepreneur.
Not really. It's really hard to try and get fired, since the employees are protected pretty well. So in order to get fired you would have to mess up pretty bad, to a point where you would usually leave a lot of scorched earth, so very few people do that.
If you are on good terms with the company you can also "get fired" (I've heard of that in a few startups), so you can collect the benefits, but that only works in a small set of companys I think.
You can't just stop doing your job, show up drunk, and yell obscenities at your boss all day. Well, you can, but you probably won't get unemployment benefits.
Sadly, I have not just one - but two friends who have lost their jobs for showing up incapacitated. One wasn't alcohol, though. They were stuffed full of amphetamines - but the first one was drunk. Neither mentioned any employer offers of rehab.
