The US is not a “conglomerate” nor is it different countries. You do not have a passport from your state and if your state would seceede there wont be many international recognition.
Also it is quite telling that you say that you have these rightsin your state, so workers who dont habe them shouldnt fight for them. Then again i think you just saw recently in the abortion decision of the supreme court, why it is dangerous to leave these things to the state level and not have them on the federal level or better yet constitutionally protected.
