Hoping to get some unbiased opinions on this ongoing rollercoaster I'm dealing with at work. I'm currently in a senior position, directly reporting to the execs and tipped to move up to exec level in the next few years. I oversee a team of 5 and for the most part it's a fantastic team- couldnt be prouder of their dedication to getting the job done and their attitude at work, with the exception of one colleague.
She was hired a few months before I joined ( just under 2 years ago) by the previous person in my position who then opted to leave for an opportunity too good to pass up. She was hired in an assistant position as she was still completing her qualifications (we are in finance) with the goal of her completing and dropping the assistant title, progressing etc as the normal path in finance.
However it's just been an absolute rollercoaster managing this person over the last year or so. We have had several instances where she missed deadlines and have had to be gently nudged to complete tasks (she cited month end as the excuse but we all deal with month end and get our regular tasks done). There have been times where she has just checked out from the team, not really contributing in team meetings and citing that she doesn't feel apart of the team, so much so it drove myself and another manager to begin having twice weekly check ins with her to motivate and keep her in the loop as much as we can.
The pace at which she completes tasks is also questionable. For instance I passed on one month end task to her to have a go at for a few months in the name of progression. It took her 6 hers to complete while it takes me less than an HR. Granted I do have more experience but even accounting for the experience gap, using almost a full workday for one task that takes others an HR has a huge impact. After a few months I ended up taking the task back because it impacted the entire team competing their tasks.
Late last year she applied for an internal position (a step up) and I supported it, even working to coach her for the interviews. In the end, someone was better suited sadly (and has truly shone in that role). In an effort to continue encouraging her, i have worked with other managers to get her on ad hoc projects to give exposure. This turned out disastrous as she didn't even respond to the email for 3 weeks. In the end , someone helped and has gone on to own that project.
Recently she has just not shown up to 1:1s and cancels meetings she would lead with no explanation. Refused to join the team meeting saying it offers no value to her. She has become very standoffish with me, wouldn't even acknowledge a good morning in the office from myself. Last week she was off sick and did not even inform me. I found out that day through the HR system after which I had to scramble to cover her tasks as they were time sensitive. I booked an in person check in to give her a chance to voice what has been going and speak to her about these things, reminding her she needs to attend meetings and speak to me directly if she is ill (which is not a problem I just need to know!). She has no reason why she didn't attend the check ins etc.
A day later I have found out she has been speaking to others in the office saying she doesn't like the working relationship with me and I make it difficult etc. however it's not to HR or anyone else where she is looking for action like a mediation to voice her concerns or request a manager change etc. she has also never voiced anything in the check ins twice weekly for months! Multiple sources have now fed this back to me. A fellow manager also flagged that she has been mentioning she would like to take on some tasks I do. However she never voiced it to me. I'm due to have a check in with her tomorrow and I'm at a loss at what to do with this one. As much as I have tried to be a kind manager and encourage her progression I feel I'm not getting anything in return to work with. Thoughts on how to handle this please? For context, she and I are similar ages and she holds a master's but just hasn't completed her chartered qualifications. She mentioned this as a comment.
Sorry for such a long one!
