I was recently offered a position of managing 3 individual shops in a shopping mall. Before me, there were 3 other store managers, one for each shop. All three of them transferred or were fired, each for different reasons. Since then the assistant store managers have been responsible for the shops before I took over.
I am facing a problem with one of the assistant managers who was expecting to be promoted to manage her store, but the company instead gave all 3 positions to me. She acts bitter and refuses to co-operate and does everything on her own without informing me. On top of that, she has accused me of being rude to her - which I am not - and I have been called for an HR meeting regarding "my behavior".
I really don't know how to handle this situation, as I have never even had an argument with her during these 3 weeks. I also feel also embarrassed for being accused of being rude. What do I say to HR? How can I deal with this assistant manager?
