How do I stay civil with a colleague after she caused extra work on purpose?

[Travel11]

About 2 weeks ago a colleague I sometimes sit by kept asking me questions about a task the manager does. I told her I don’t know as I am not involved. For some reason she kept pushing the issue as though I needed to be involved. I changed the subject. Next thing I know she sends an email to me and the manager about this task as it’s a reoccurring one, my manager has now delegated the task to me. I am furious she has dragged me into this. I had already been give more work and now I have this to do.

Today I sat elsewhere at work and avoided her. The manager has said recently he doesn’t want me sitting with her and that it’s best to sit with everyone else in the office. I know it’s best to mix with others. The rest of the team don’t like her as she is obstructive and argumentative. I don’t want to sit with her again as she has betrayed me and crossed boundaries. How to I keep it civil but not let her back in like I was friendly before? She is a liability.

Thanks.

This sounds like somewhere I used to work!! Someone did similar to me...but I did the task, and also used it to show what the colleague wasn't doing, and how they were also making certain tasks take longer/more steps than they needed to be as as not to take on anything else - but also to make out like only THEY could to them.

They gave me the pot and the spoon and I stirred it!

But how to handle them...Just don't talk to them unless absolutely necessary for part of the job. Don't say or do anything else regarding them. Literally ignore they exist.

My manager did say if there are other things getting in the way of this new task they can be moved to the rest of the team. So she would end up with something else anyway.

I just don’t understand why she put me forward as anyone could have done the task. She always tries to involve me and tell me about things that are not to do with my role. I am lower day than her and we are not in the same salary so higher responsibility task should be remaining with higher paid people. At least if I sit elsewhere she can’t try to keep having conversations about me doing other people’s work.

I think she enjoys people struggling as she always argues with other team members who can’t stand her.

My manager doesn’t want me to sit with her. She even rows with the manager and we have heard her.
