What is Your State? Most States have it codified somewhere. The labor code is a good place to start. An employer has to inform you of the type of employment relationship due to the difference in those relationships. Employment "at-will", is what is mostly common in our Republic. States can proclaim their own rules. At the will of either party, not Just and Only, the employer, for unemployment compensation purposes. And, for fiscal advocacy purposes; a general tax could be used. The general fund should be used to promote the general welfare.
Which ones do not recognize at will employment? Tell me if an employer cannot fire you unless he has cause why should you be able to quit unless you have cause?
Montana was the only State not resorting to the doctrine of employment at will, last time I checked. Can you re-state your position; it doesn't seem clear to me. I may misunderstand what you mean.
I don't know of any states that do not have a basis of employment at will, there is enforcement of employment contracts which may stipulate some firing for cause exemptions but we are an employment at will country. My question is pretty clear. You seem to be wanting some firing for cause instead of firing at will. So tell me if an employer cannot fire you unless he has cause why should you be able to quit unless you have cause? I mean if you can walk into work Monday morning and go to your boss and say "Joe you know I really don't like you and like working for you so I quit" and walk out the door leaving him high and dry then shouldn't Joe the boss be able to say " you know I don't like you working here or working with you, your fired"? Should the boss be able to go to the government and sue you for wrongful quitting your job?
I thought I answered that specific question. EDD has to Prove for-cause employment, to enforce for-cause employment stipulations.
