Hi Lola,
When i mentioned legal insurance i wasn't reffering to FR, it's just an opinion of mine, that everyone in this industry should get it.
As for medical insurance, it depends on the country you are based in. I have an european health card that givese me the right to be treated,if needed, in all EU countries. I am not very sure how i got it but i'll look into it and let you know.
As for sacking people, it's not for "no reason". Most of the FR CC are very, very young and unexperienced in life. They are the ones to get the sack because they decided to party all night before an early shift (that starts at 5.30am roughly) and they are either still drunk or very hungover. Or the ones who pull one too many random sickies or they just don't show up for work. It's a shame really but they need to be tought a lesson, so sack'em if they don't want to work!
If your course starts in Sep, i suggest you go for it. You don't have much to lose apart from let's say money, but it's an experience and you can decided for yourself if you want to stay or leave. But then again this is only my opinion, it's up to you really.
Hope this helps too. Anymore questions please do ask.
Rgds,
ATS
