I've worked in the same role for 4 years and within my department for 9 years now . When I applied for my current role a woman who had worked for the company longer than me but on a lower grade applied for the same job and didn't get it . She now manages a department within my current job but has no real working links with me except being in the same building (she works in admin I do something quite different ) . It's got to the point though where I cannot stand going into work because of this woman . She has to use some of the space in our office and when she comes in she greets everyone else except me she slams doors and huffs and puffs and constantly makes digs about me getting paid more than her . Our company has a flexi time policy and as I'm usually in early I usually leave on time as all our work is more than done and this also attracts snide comments from her about part time working despite me having checked with my own manager umpteen times if I can generally flexi out once work completed . In general she is a very bitter person I have tried more than once to get along with her and every time it comes back to bite me in the face , usually whenever I think we are getting along the next day she will come into work in a mood and make her comments . My other colleagues work on a rota system so although they notice her attitude they don't feel the impact of it as much as me . I am good at my job and enjoy other aspects of it except this woman . I've spoke about her to my manager but from what other colleagues have told me the manager won't do much as they have worked with her in a previous life and kno what she's like and don't want to risk upsetting her . Apologies for the long post but I've had a rotten week with this and it's getting to point it's taking over my out of work thoughts too .
