The an_cap position on immigration is open borders which is the opposite of "people who can be deported if they complain about their working conditions". Feel free to check the comment history.
Take it up with your fellow “caps” then, they’re the ones that support expanding this category of workers that have fewer political rights. The labor unions clearly only about immigration issues insofar as it relates to trying to weaken labor laws.
You were the one who changed subject to be about “switching jobs”, presumably because that issue has less to do why companies want to hire non-citizens in the US. Up until that point we were talking about employees advocating for rights at their current jobs, which is the main thing undocumented workers or people on work visas have to worry about. You were clearly trying to go for the “just change jobs if you don’t like your employer” thing, which is why you changed the subject (and then accused me of doing that, for some weird reason).
