I recently transitioned to a new team after spending two challenging years in my previous role, where I faced significant conflict with a senior colleague who exhibited sexist behavior. My manager intervened multiple times to resolve these issues, and shortly after a particularly intense disagreement, I was informed that I would be moving to a different team. This change coincided with a reorganization within the company, and many members of my old team, including my senior, were also being reassigned to new projects. I was moved to a new manager as well. Since joining my new team in January, I have found the environment to be much more positive and supportive, allowing me to explore new responsibilities and grow professionally. However, I recently learned that one of my teammates from this new team was laid off, which has left me feeling uncertain about my own job security and how my recent transition might be perceived. As this is my first job, I'm unsure if these kinds of changes and layoffs are typical.
