I work at a small company. A few years ago, I was chairing a staff meeting when a male. colleague and I engaged in an argument about a client. The colleague became angry, called me an expletive and stormed our of the room. I immediately told HR and the head of the company. They sent the offending colleague home for the day and said they took care of it but he refused to apologize. We do not speak to each other and it’s uncomfortable to work there now.
