I work for a small company with a flat structure, with our company president as the lone official manager. There are ~25 employees.
Several years ago a pair of coworkers (let's go with Alice and Bob) started a relationship. During the time of their relationship Alice had a increasingly antagonist relationship with another coworker (Charlie). One whom Alice must work directly with (they are in the same department).
After a workplace disagreement between Alice and Charlie, Bob actually called Charlie at home to discuss his unhappiness with the way Charlie was treating his partner Alice.
It is my judgement that - given what I know and can verify - disagreements at work may have been many and with emotion but not necessarily unprofessional (to that point). I may not have complete information.
The call at home only led to further problems. Last week the company president met in private with Alice and Charlie to discuss a recent disagreement. It got heated. Past the level that I would consider professional. It may have been the only time that I can remember in 11 years with the company that the president ever raised his voice back. This was mostly the president and Charlie.
That being said, I do not believe the president intended to fire/remove anyone. But today he fired Charlie, apparently because Alice or Bob stated that they did not feel safe.
Given what has happened, I am concerned that a disagreement between a coworker and either Alice or Bob would be at risk of involving the other partner again and it getting personal (someone else getting a call at home). Do I have the right to ask my boss if this has been addressed? It is common knowledge at work this occurred.
After the termination I do not feel as comfortable dealing with either of them now. How can I address this?
