i started a new role in november of last year as a teaching assistant in nursery. Our staff team in nursery consists of 1 teacher and 4 other teaching assistants as we are of a large scale. i am sharing a carpet with one particular member of staff who is making it downright obvious she does not like me. She will totally ignore me, chooses to shout to other members of staff to help her when i am standing right there, when i offer my help she replies coldly "no!" however chooses to ask others to help her, never passes on information to me she hears about school and even when i ask her she will not give me eye contact and tries her best not to answer me. I fully understand that in a workplace u cannot expect everyone to like u, i have spoken to the teacher who passed my concerns onto the head of year who's reply was "its just her" however this situation is not getting any better, today for instance i was in a room with 3 other members of staff when this particular member of staff walked in and told them all valuable information and i had to ask her to tell me as she was leaving, i am beginning to feel i am invisable and totally unworthy. I spoke to the teacher and suggested i invited all staff out for an end of year meal, only to find they were already going and i was not invited, this in itself was upsetting and has concreted my already worrying thoughts. Any suggestions on how best to deal with this upsetting and awkward situation would be of a great help, i feel like my head or head of year could be offering me more support, or at least talking to her about her lack of teamwork, am i wrong to be thinking this?
