I work in a professional corporate environment in a senior position, not the department manager but work at equivalent level and have a managerial and supervisory role in relation to junior members in the team. One member of the team does not pull her weight. She does less and it is lower quality work. As part of my role I manage and train people but this individual seems to complain to her team manager any time she is questioned. The manager appears to see the issues but it is becoming so tiresome feeling like whatever I say she's going to complain. Some of the things she complains about is ridiculous and she even seems to have a habit of calling the manager , crying, which even the manager thinks was odd.
Today I questioned how long it took her to do something, questioned further when she gave an answer that didn't make sense, but ultimately left it as I didn't want to outright accuse her of lying or making something up. Today she's claiming she can't help me with her usual work as she's busy doing other things so I am guessing she's complained and ask not to work with me. It's probably not a bad thing but after an otherwise stressful week at work (could do a separate post on that but I won't!) I just feel frustrated that part of my job is developing people but it's difficult if you meet resistance if you do so much as question or critique something!
