Managers need to be aware and provide a workplace where people can communicate negative feelings without fear of reprisal.

A lot of the anger we came across was more the 'sapping of energy' kind rather than an explosion of energy. The question is what are the effects of this accumulating anger over time and how does it lead to outbursts?

The more you feel anger, the less likely you are to put your best effort into the job and the less likely you are to tell an employer that there is a quicker, better way to do your job. These are sins of omission, rather than commission.
