For employees deciding to quit, for any reason: I don’t care. People quit jobs for stupid reasons all the time. Sometimes the stated reason for quitting is just an excuse to cover for other reasons. As long as what they do for a living is legal and as long as they aren’t relying on tax dollars to support themselves and their families, their decision to quit is their prerogative, imo.
For employers with race/gender/sexual-orientation-selective hiring practices: I support the right of private businesses to hire whomever they want; I also support their right to NOT hire whomever they don’t want. However, their market may respond to their hiring decisions in unpredictable ways; consumers can be very fickle.
