I had 5 months mat leave, came back to work and everything changed. New members of team joined and my mat cover stayed. There was opportunity to become a team leader for different departments as the company has broken down into departments. I applied for team leader for the department I always worked for since I started. My mat cover that stayed got the team leader role for my department. I got really upset and I told my manager how upset I was but unfortunately the reason I didn't get the role is because my mat cover spoke about everything a team leader does and I missed the point about 'people'. Because of how upset I got my manager told me to consider to get a mentor and decide which department I want to work in and he suggested for me to change my career path. I really need help to understand why my manager told me to get mentor only cuz I showed my emotions for a role that I really wanted? I understand having mentor is good but I am trying to understand what did they see in me for him to say I need a mentor? Help understand?
