In this situation where a younger supervisor is managing an older, more experienced subordinate I would recommend that the younger supervisor acknowledges the subordinates experience, and is upfront with them about any problems that may arise as this would create a smoother relationship between the two and would allow them to better work together. Specific to the case study, instead of simply firing him/her or giving him a warning I would advise him/her to speak with him/her about what he/she is not doing well, and see if he/she believes if that is something that he can change. If he/she admits that his/her current position is something that he/she can no longer be successful in then it is possible that the company could find another position for him/her, considering that he/she has been an intergral part of the company for many years, and there are people that are loyal to him/her.
Heidi could tell their softball friends that she has a goal in life or a resolution to reduce the amount of curse words and he had set up a limit of bad words and she could try to involve her friends and explain why according to his principles cursing is so bad. Another thing that she could do is convincing their coach and the people around the sofball game to take the same course of actions explaining why she made her resolution.
