You're not alone. In a survey of British workers, half said that they have come close to punching a colleague. Common occurrences such as a faulty computer, too much work and annoying workmates were the main cause of "office rage".
Cut tension between you and your colleagues by avoiding gossip, talking to managers about your frustrations and not disturbing others while they work. If you're the boss, it's important to recognise and sort out conflict early. Also take staff complaints seriously, avoid overcrowding the work space, and set realistic workloads and deadlines.
