I have always found that the straight forward approach is always the best. Simply walk up to the group and explain that their language could be considered by many as offensive and as such can not be tollerated in the work place. Offensive language whether directed at someone or merely as a part of the work environment can not be condoned or ignored by management.

Many people disagree with the use of profanity these days. Does your company have a policy that prohibits it? If not, you might suggest one. If the language creates a hostile and offensive work environment, you might consider reminding the offenders of your harassment policy.

This is definitely a problem in the work place. In a previous job, I had an supervisor who was the main culprit. I finally asked if I could speak to him privately and asked that when he is speaking to me if he could not curse or swear. I do not speak that way to you and I do not wished to be speaked to in that manner. He apoligized and it never happened again. However, he still spoke to my colleauges that way and my colleagues were speaking that way too. Eventually, someone from another department complained and the Senior VP of our division held a held a meeting and spoke to us and implemented the Lorreta Young idea and things really improved.
