Once you realize you are at a company where telling the truth leads to a negative consequence (an incompetent manager hired after the truth told. Their first time managing a department. The department did not previously exist in the enterprise.
The department is specifically to roll out a technology they have never worked with before throughout a large company.
Lets say you were in charge of the project, are intimately familiar with the technology, and had a clear plan that would lead to success but upper management wasn't happy with the timeline. Their goal seems to be to quickly complete this project to display it as a "win".
Now the new manager was brought in, does not understand or care to understand the complexity of the project, and just keeps asking "when will it be done". Then got tired of that and changed to have it done in 2 weeks which is unreasonable, and then gave you an entirely false, negative performance review based on information they apparently forgot to actually verify or they would have known it was already complete and the people who were on the receiving end of the product are incredibly happy.
HR is asking for a meeting to discuss, what do you do?
Tell HR about the depth of the incompetence
Tell HR you weren't getting support from upper management
Tell HR to look into what on earth was the reason this specific manager was selected.
or
GTFO?
This is a real life circumstance I am dealing with. I believe in the technology but unless changes are made it will be a guaranteed failure. Upper management likes the technology and really wants success here, but I know it wont happen unless then changes are made, and the people between the senior executives and me are making it impossible to be a success.
