I don’t have any numbers, but some job postings will say full time, part time, or will have a minimum number of hours they offer. Some will also give a percentage range of hours they offer of part time to full time.

If the posting doesn’t say, I just brought it up during the initial call so we were on the same page before continuing the interview process. Most German companies didn’t have a problem with it, but I found that UK and US companies did.

Keep in mind working hours are fixed in your contract and it’s not unspecified like in the US.

In the Netherlands, the right to work part time (at companies >= 10 employees) is mandated by law. So every single job is this type of job.

At the Engineering firm I work at I would say roughly 30% of employees work part time.
