It’s very easy to criticise and put people’s moral down. The problem is we don’t know how much damage it can cause to that person. But it will be remembered though. However it is also easy to praise people as well. Just say positive things to people can go a long away even its small things. They will appreciate it more and gives them a boost as well. If you struggle to do this then pick out something and say something good about it. Even doing a good job or a win/point for the team will give them a boost. Also it will give you a boost as well. So a nice challenge to everyone praise and/or acknowledged people at least three times during the day and if you say a negative thing or put people down the penalty is three more praises/acknowledges. Good luck.
