Belgium - 13 years in the position, simple IT Tech: I have to give 13 weeks notice if I quit. I'm allowed to take a (paid) day off each of those week to look for a new job. If my employer fires me, he has a 42 weeks notice to give me, I'm of course also allowed to take the day off every week to look for a job.
