First time poster but need some advice off please.
To cut a very long story short, I work with a woman who is so unbearably lazy and rude it is having a negative impact on my mental health. It came to a head this week where I felt she massively undermined me in front of more junior staff and instigated what felt like a pile on on me.
Management are aware but seem unwilling or unable to do anything about it. I do love the company and other than this woman everyone is lovely but she will never change and I can't work with her anymore so I feel like I need to move on. I don't want to raise a grievance as I am not sure what this will achieve other than her being even more unpleasant than usual, other people have complained about her and nothing changes.
My question is, should I tell my line manager (who I get on very well with) in advance that I am looking for a new role because of her? In an ideal world I would move to an internal job but it is a small company and they don't come up often, but roles have been created to stop talented members of staff leaving before and I know I am well thought of. I have applied for a few roles over the weekend so should I wait for those to pan out before I tell them how unhappy I am and that I want to move? I don't want to look like I am throwing a hissy fit or making threats but at the same time I would like the chance to stay with the company.
Thanks in advance for any wise words.
