In Switzerland jobs are usually advertised in %, where 40h-45h/week is 100%. From that it is also usual to talk about 80% or 4/5days/week (and so on for other percentages).
Only if you consider 32/36 hours as part time - the culture is strong in the sense that those are often considered full time as well, and are therefore allowed, but getting a job with fewer hours than that (eg for a three-day work week) will be a lot more difficult.
