Why do so many people hate unions? I'm guessing they're all on the Right, but what is so terrible about workers having rights?

All over the internet people are giddy that the Federal workforce is facing elimination. They don't care what it does to our country, all they care about is that that savings can be passed on to the 1%. I seriously think these people are the product of siblings mating (i.e. Magats). Unions protect the rights of the worker. I can't understand why so many people are against workers having rights. I mean the alternative to collective bargaining would be a non-union workforce gets pushed too far and quit en masse. Would that be better for companies? Unions can negotiate, unions can cause a little discomfort with a strike, but a mass-quitting could ruin a company. Like if the entire Federal workforce, and let's include USPS were to quit tomorrow, I am pretty sure the country would stop functioning. There's no short-term solution even if you used the military to fill all those vacancies. Imagine ads saying "Wanted, temporary CIA agents, will train". lol

It feels like cruelty. Anything at all that benefits the 99% in any way, half the country is vehemently against. The biggest thing that gets to me is beyond the cruelty, THEY think if they can just transfer the rest of the nation's wealth to the 1% that people like Musk will start showing up at certain doors with a million dollar check welcoming them to the 1%. Or maybe they're not that dumb, but they think they will be in the 1% at some point and all of this will benefit them. But they most likely won't. And all they will have done is made their own lives worse. Like all the people that voted for the guy who's in charge now (apparently his name is forbidden here in posts) who are now losing their jobs. They exercised their rights, and now they're filling out unemployment forms. I wonder if they're happy with what their votes got them.
