I have been working in a US-based company (> 70,000 employees worldwide) in China for 2 years as a data "scientist" for business/commercial analytics. Recently the new coming team leader finished her 6-month probation and entered a long-term contractual position with this company. She acted "perfectly" professional (e.g., effective communication, quick catchups with projects and paying attention to computing details) in the probation leading the team.
Just as she passed her probation, the issues of toxic behaviors suddenly emerged.
- Constantly not even up in the office and meetings, saying herself is in another "important meeting" which is not recorded in the meeting scheduler, this introduced significant unnecessary communication difficulties.
- Cancelled all weekly meetings as many analytical projects between technical colleagues need to be synced.
- Copy and paste email contents from the data science colleagues and forward out pretending it was her idea or input, and showing off in the meetings with other internal non-technical audience, without any acknowledgement.
- Have no transparency with the information coming from her manager (the management).
- Failed to pay attention to the technical tasks.
- No plan for the new year working priorities.
- Have trust issues on the technical results for no reason.
Currently there are ~5 colleagues (data scientists and engineers) report to her. I was wondering if it is possible for me to professionally handle this situation.
Thank you so much for reading this.
TL;DR: How to professionally deal with that my new manager acted to be professional in her probation. After she passed probation, she starts to not do well in her job and ignore almost all responsibilities. No guidance, no management, no planning, no transparency, not showing up in person and plagiarism of other people's work.
