I am a secondary school teacher, anyway there is this young colleague who is in the next room to me and yea she is lovely to the kids, something that just is not in my personality as much and this is a tough secondary school. Anyway, yesterday i was taking a troublesome girl down to my class for detention when the girl started walking and half ignoring me. I told her to come back and colleague appears in front of the boss and uses her soft voice to get the girl back when i wanted to handle it myself. This was all in front of boss too who was in earshot and i was so angry at her interference as i have had words with this colleague before over her interference buut do not want any more conflict and i just felt she stepped in. What do you think?
