Myself and my colleague work on a specific project which is broadly the same as the rest of the wider team. We have our own caseloads but do a lot of shared work such as stats and presentations. We get on very well despite being total opposites. I'm extremely organised and self conscious about my work whereas she is a massive piss taker and very disorganised.
To give a bit of context she's permanently really late, dresses very inappropriately and continually misses her deadlines. Our boss is very laid back and generally if there's reasonable output he doesn't mind. All of the above though is in such excess they have been addressed with her numerous times but more formally recently. She doesn't get it though and I think feels that she's getting picked up for not performing to the standard I am - which isn't amazing but is good enough. I feel she is becoming resentful of me because of this. The rest of the team are also continually commenting on her skiving etc which I stay well out off.
We schedule our own external appointments but recently she has been ringing me or texting to tell me she's going home early but it's OK because of such and such, she's wearing these trainers but why it's ok.
It is nothing to do with me. I ignore it but now I'm getting really paranoid that she's purposefully trying to involve me in a "well I told Pink" type of way. Today she text saying she was going home an hour early because she didn't feel well but she had took a photo outside the external office yesterday to show the boss she had stayed late so she wouldn't be making the time up. I really don't care. At no time have I given her the impression that I'm keeping tabs on her. We've both been there a year, her eight weeks before me.
It'll cause awful bad feeling if I bring it up to my very approachable manager as we do have a fair amount of shared work but if I don't I know she'll try and make it out to be my fault somehow. In the past she's tried to throw me under the bus for things that are absolutely none of my business, which thankfully the manager saw straight through. What do I do here that won't cause a row but will keep me right?
