The Baltimore Symphony Orchestra fired flutist Emily Skala, partly because she advocated right-wing politics, but also because she refused to wear a mask.

Wearing a mask is an important safety precaution, and firing people for refusing to do that is entirely justified. They should have offered her some other way to hand in her tax document, but I don't think she could have done her job without wearing a mask.

What she said is another issue. I disagree completely with her views, and I condemn her reported bigotry. However, it is harmful to society for employers to impose political limits on what employees say outside of work, unless their job is to speak for the organization. We see an increased tendency to restrict employees' political expression. This does not violate the First Amendment, but freedom of expression goes beyond the First Amendment. Restricting employees' freedom of expression makes society less free.
