In the UK there's quite a lot of legislation to protect part-time workers, such as:

(a) you're not allowed to pay them less than full time workers (per hour)

(b) when recruiting, you can't say a post has to be filled full-time without having a demonstrable, objective business reason

(c) existing employees have a right to request flexible working hours

I don't think UK business culture has yet caught up with this legislation, but it's possible that mixing multiple part-time jobs with flexible hours could become more mainstream over the next decade.
