“Part-time workers cannot be treated less favourably than comparable full-time workers solely because they work part-time, unless it can be objectively justified.”
So, employers can deny requests for shorter working hours, but only if that can be objectively justified.
In general, that’s fairly hard to do, given the amount of part-time workers and the diversity of their jobs already in the market.
Also, when I was considering moving to the Seattle area, I got the feeling that non-compete clauses were fairly standard, although, that is entirely subjective and might be incorrect.
Both Oregon and Washington are at-will states, and have the same laws with the same kind of work cultures -- you're a cog in a system, and if you start grinding or upsetting the status quo in some way, the candidate pool in this region is strong enough, they'll replace you. However, the expectation still remains that when you choose to exercise your same rights under at-will that you give two weeks notice. Can't say any employer is going to give an employee that same courtesy when letting them go. Not to mention if you're salaried, you might as well accept that your role is nothing more than indentured servitude branded as capitalism (to clarify, this may not be at all companies, but definitely is a strong cultural trait I've seen at the ones I've worked at).
All that being said, the PNW is much prettier than many areas of Texas, and while natives are hostile towards transplants, the quality of life is leaps and bounds better than that horrendous mass of land called the Lone Star State.
This is a page from the government describing your rights: https://www.rijksoverheid.nl/onderwerpen/arbeidsovereenkomst... (you can translate it)
I understand that it is fairly strictly enforced, so an employer saying "no sorry, that would be annoying" won't fly - they would need a concrete justification.
Is this actually a thing? There are laws regarding this? How do these laws work if there's a job requirement itself which needs certain number of hours?
