I retired as a programmer five years ago and now I drive a school bus. The difference in acceptable workplace behavior is pretty stark. In my software companies, nobody ever came anywhere close to saying anything even vaguely racist; meanwhile in the bus garage people routinely use the n-word and the g-word. And it's not like this is Mississippi or anything - this is a suburb of Philadelphia where the entire transportation department would probably be sacked if parents were ever to become aware of how their bus drivers talk.
