I work with this woman at work. She is an EA to the MD. She snitched on me at work to HR because I was 'short' with her - i.e. I tried to shut down a conversation with something that had nothing to do with her. My boss and also HR manager whom I suspect doesn't like her either - told me to apologise to keep the peace even though I had legit reasons to wind that up very quickly. I also told them she has rolled her eyes at me a number of times and has been rather curt with me. I don't mean it to be tit for tat but she needs to be careful what she wishes for.
I'm the office manager, and she challenged me on which dept looked after what, which is something that has NOTHING to do with her - and then she proceeded to give me a direction on what to do next. She isn't my manager. I don't report to her. The only time it's appropriate is when her boss is hosting something such as the Xmas party, end of quarter morning teas etc. Not the day to day running of things. I've been in this job for 12 months - so I now know the lay of the land.
She once a couple of months ago tried to reach into my drawer where I keep security passes and told me to give this random (whom was signed in as a visitor) to give him a pass (these are expensive and I don't want too many floating around in case you forget to switch them off). This wasn't her visitor; he was a contractor who was on-site during the day. I told her is was all under control and she got upset. She also told me that putting something in my back mailroom would crowd it out. Again, nothing to do with her. She also CC my boss with a pre drafted email message to send to people when parcels arrived in the office - I hand deliver parcels and parcels are not getting lost - this was prompted by the fact that someone had to chase up if a parcel had been delivered or not - she told the person it had...but she didn't leave it at that - she then drafted that email message I should send to people when they have parcels arrive.
I'm worried that she has legit grounds to tell me what to do - that hides behind powerful people to give her snitching legitimacy. So...what are your thoughts? I know I have to suck it up, but I how do I deal with this person?
