Just now I have been promoted as Team lead and from Senior Web Developer. Actually I have been promoted due to my good technical knowledge, but now my managers expectation are very high as "Team Lead". The issue is that in my previous week I have given one task estimation and that estimation was judged as Over Estimate and now my manager has forgot my all good work and only recalling overestimation thing in each every discussion. I am feeling bad that how one mistake can erase all good things. Actually I want to learn the professional way to handle such situation.
So my question here is how to handle scenarios like on I mentioned above ?
How to handle project manager who is always on fire now?
I am loosing my interest of work due to this issue ?
Even she is criticizing now on my every task and judging me like a hell.(she is non technical)
