Then again, I've also read in the news here of employers hiring private investigators to catch employees fraudulently claiming sick leave, then firing them and suing them claiming back wages paid along with the P.I. fees.
To play the devil's advocate, since sick leaves are costly for businesses here, it probably sucks hard if you have a few employees abusing it heavily to avoid work (even though it's common knowledge that everyone here takes a sick day off work every now and then after a heavy night out partying and drinking or stuff like that).
But you are! Lots of things can be improved in lots of places, but the problems with US labour don't exist and are mind boggling for developed countries. I'd (and I'm willing to bet all those rail workers would too) a potential egregious invasion of privacy to validate I'm really sick in exchange for pretty much unlimited (details vary by country, sometimes after days/weeks/months you're moved to like 60-70% salary) sick time, instead of no sick time at all.
In Dutch employment contracts this doesn't even have to be specified, this is a general condition applying to all employment contracts. Most companies won't actually send a doctor over until you've been sick some time but they always have the right if you want to continue to receive sick pay.
