I am currently a remote employee in CO (employer is in AZ). I want to switch states to OR (my employer already has remote W2 employees in OR). My employer already pays state tax there, insurance etc. though they have no building there just as they have no building in CO. Theoretically, there should be zero difference to them, I have confirmed this with payroll. I have confirmed with my manager, and that individual could not care less where I live. I have also discovered, their per-employee cost basis (for remote) is lower in OR than in CO.
It does require a lot of approvals however in our system to change my W2, both with payroll, my manager, my manager's manager and the HR Director + a few others. Some of these individuals are a little personally put off that I'm moving to OR instead of AZ where headquarters is at. If at any point along the way I am denied (I can't think of a valid reason), do I have any legal recourse to force the issue - would it be worth the attempt? Can a company let me go for no other reason than - I moved to a location that hurt their feelings? For example, can my employer say: "We never offered a job to you in OR"? etc.
