I get some people have immense faith in capitalist rule, that you genuinely believe that the reason it's normalized to not discuss salaries or politics is for your own good. Some people don't believe in class antagonisms. This used to be a purely fascist position, but liberals adopted it in the mid 20th century because of how effective it is at driving complacency.
Politics used to be common in the workplace. Not necessarily electoral politics, but organizational politics, which is far more important and impactful, and also much more regulated by capitalists and the petite bourgeoise. I've talked to my boss about electoral politics before, and it didn't cause issues. If I brought up unions with him I'd be fired within a month (based on how other union organizers were let go).
