36 hours per week. 25 days vacation (going to 28). Pension contributions. You can buy extra leave. Epic location, fun job, decent salary for the UK (where e.g. you don't pay for healthcare)...
It's not "medical reasons"; it's overwhelming government bureaucracy in the UK. A friend of a friend broke his shoulder and collarbone over 14 months ago; he needs a new shoulder. He's been in a sling for over a year. Every couple of months, he gets a call asking if he still wants to have the op. It's disgraceful.
Talked to a German guy who was here on holiday recently. When I told him that in the US it's typical to get two weeks vacation when starting a new job, you should have seen his eyes bug out. It was hilarious.
