I was saying that it seems better to have the PTO days to use however you want than sick days that aren't supoosed to be used for non-sickness reasons.
Are you saying that it is normal for people to use the sick days when they are not really sick?
You mention needing to consult a doctor at a certain point. This is not uncommon in the U.S., with the employer wanting a doctor's note after more than two days of absence. (As an aside I always thought that was a burden on the employee, to have to pay for a doctors visit because the employer doesn't trust them. Not as big a deal if the employer would pay for the visit, but they don't. Certainly not a perfect world we live in...)
