I think my sense of professionalism and appropriate office etiquette has been skewed by working in some very diverse environments, so I just want to get a reality check.
I work in an open plan office that ranges from half full to overflowing with staff depending on the day of the week. One member of staff has expressed (since they started) an issue with noise and being unable to concentrate when people are noisy. (However, the same colleague is apparently unaware when they are loud on the phone or in conversation)
Yesterday, it felt like out of the blue, they leaped up shouting at another colleague "I've told you over and over again to be quiet" and carried on ranting. Manager came between them and remonstrated and colleague continued arguing with the manager before storming out of the office.
The other colleague was in tears most of the day.
I don't think either colleague can change the way they hear or speak. If something like this happened in your place of work, what would happen?
