I hate when I have to disagree with my boss - she comes up with ideas, and I often think of a better way, so I present that to her or in a meeting as an option. Today, I need to pursue my own idea vs her idea in a meeting with a colleague. This takes some skill - to pretend like I am considering her idea, then opting for my own method of approaching the task. I mean, honestly, it should be up to me since it's my work that is involved. But I hate it and this gives me anxiety. Being assertive gives me anxiety at work. I always worry about my tone and wonder whether my tone is harsh when I am really only trying to be assertive. This comes from being bullied and abused at work. I don;'t know how to improve this issue.
