So I'm soon to return to work and DON'T want to let her walk all over me again. I would like to know how to handle:
When she request I do something that she can easily take care of herself (like calling the repair man who's number is posted up front).
"As you are familiar with the problem, it would be best for you to call him. His number is posted up front. Could you also make a note of the specific problem so that if you are not here when he comes, whichever iof us deals with it know what the problem is" or a more general
"No thanks, you go ahead. I'm sure you can manage" (which makes it harder for her to not do it without implying that she can't in fact, manage.
When she makes promises to customers that I'm not able to do or that would be really inconvenient.
Don't do it. To her, say "Oh dear, you need to call the customer back and let them know that isn't possible - did you forget that this is my day off?"
Do whatever it is at the appropriate time. If a customer says that she promised them you would do it, then you reply to the customer ""I'm so sorry, I have no idea why [name] would have told you that I would do that, that was never a possibility as Monday is my day off (or whatever). I'll mention it to her, as of course she should have called you back to let you know she had given you incorrect information"
When she makes comments that she is the only one who does work (I usually ignore her and walk away).
I'd try to respond with something light "Oh, I wish that were true. I could do with the break!"
If she continues than I would actually call her out on it "What an unpleasant thing to say. Why would you want to insult all of your colleagues like that?"
What to respond with, if anything, to "I know what goes on here at night." (shall I cheekily reply: "wonderful! please make me a list of issues so they can be addressed!)
[smile] Well of course you do. So do I, so do we all. It's pretty much the same as what goes on during the day. Of course, if you mean that you think something goes on which shouldn't, then of course you need to let [whoever is in charge at night] know, so they can address it.
I would also stsart to document her behaviour and encourage your colleagues to do so, and condider spekaing to the owner together, so it is harder for them to claim / suggest that it ios you, rather than she, who is the problem.
