life, distributed a company wide memo that stated that using language that was sexual, including the f-bomb in front of customers or employees could, in some instances, be considered a "hostile working environment", and open the manager and the company to sexual harassment claims.
Some managers had to swallow their tongues, some had more success than others, but cussing dropped appreciably in staff meetings. In private conferences behind closed doors without women present, not so much. This was probably a good 20 years ago, BTW.
