I've been having a lot of stressful days at the nursery, and it's clearly due to one person-who is my room leader-taking advantage of me. I need to know how to be a bit tougher, and "not so nice", so that people like her won't walk all over me all the time. Trouble is, I've always been this way, and I've always thought that it's just easier to sort of just go with the flow. On the other hand, this person seems to like barking orders at me, whilst doing nothing herself. I didn't realise it till tonight, but, other work mates have noticed it as well. I've mentioned the situation to a person who is in a higher managerial position than the room leader, but, I don't know if anything will be solved. How can I adapt myself to work with this sort of person, so that I still keep my integrity, but, don't get over shadowed or taken advantage of further?
