So I‘m an external working at a large bank and our internal project manager is the most unprofessional dickhead. Today he threatened me to basically kick me off the project because I basically wrote him that our proposed idea is actually more efficient than what he had proposed. The guy literarily said that I was being „insubordinate“ part of my job is pushing back when we think we have a better idea/solution whatever and I‘m so tired of always having to think about the consequences in situations like that instead of sticking up for myself…how it might burn bridges, negatively effect my career etc. It‘s making me so mad but I deleted my mail response to him and just forwarded his mail to my manager, saying how unprofessional I think this is…nothin will happen, his whole team of internals is just taking his bullshit and our manager has no incentive of losing the revenue…
