New colleague since October. I've been in the job 10 yrs plus. Her first post at this seniority. Appointed with much excitement as glittering CV, plus we'd advertised before and not filled.
anyhoo, lots of overlap in work as the volume is so high. Normally pretty boundaried, ie these are my areas and those are hers, but a bit of cover needed for leave periods. We also go to a weekly meeting with the wider team to discuss progress.
at least twice now she's dropped a grenade in those meetings saying she doesn't agree with our existing policies (essentially my working style) and that we should be doing x not z. When i have approached her after i've been careful to say i am open to new information and ideas but please can she discuss with our immediate team/ peers so we can all understand and agree, and if she can get the supporting info together as to why x is better than z let's look at it. On no occasion has she actually done that, she's just said her friend working somewhere else does it like this and says it's better. I just can't work like that, i need considered balanced info to justify change.
also when she's been away i have literally had to spend hours unpicking something pretty odd she'd done on something she's been on, that had become urgent, although we as a group (not just me, and including her) had said it should be done differently to what she's then obviously gone and done. Another colleague was set to unraveling some other equally peculiar thing and found the same.
I'm finding it really stressful as she seems very personable and keen, but asks what i would do, and when i tell her she seems to be unable to stop herself arguing the toss for the opposite. I am quite confrontation adverse but think i am experienced and have evidence i am doing a good job.
seniors are pretty hopeless and want us to support her in 'cutting her teeth' and getting more experienced and obviously don't want to get bogged down in minutiae.
i've decided to swerve getting into these stupid 'asking advice but seeking an argument' discussions, unfortunately at exactly the same time as another colleague in our small team (4) has done!
I don't really know how to effectively let the managers know that this person they were so excited about is causing some ruckus without it sounding like I'm jealous (i'm not, she seems to be struggling with workload and stress (which she seems to generate for herself unfortunately)) or a stick in the mud?
