For example, that if you need to make a strong criticism, it’s a bad idea to lash out wildly; be surgical, pinpoint the problem rather than attack the person. Never ridicule a colleague, even with an offhand remark, no matter how tempting it is or how hilarious the laugh line. The more senior you are, the greater the impact your flippant comment will have. Don’t snap at the people who work with you. When you see red, count to 10.
