You, too, can do these things. I welcome you to. I will be happy to say I am wrong. Unions have real potential for creating change. I personally have no interest in joining a union for other reasons, but I am not opposed to them either.
But we weren't talking about unions. We were talking about congress. I think you will find that tech workers are not the only job segment, and far from the most sympathetic due to their wages. Lobbying for an extra day off will not get you far in the face of many more pressing issues, and the party most likely to stand up for workers is more interested in stopping data centers at the moment. Unless you're talking about a time horizon past which I don't think I'll be around to notice.
