I once had a manager who demanded I physically print all of the Kanban cards and tape them to the office whiteboard. I was told to move the cards across the board after they were moved in TFS. I still had to keep up with my other duties in the QA department too!

Despite that, I still stayed on board with the company (the pay was good, and the work was simple.) As a QA teeter, I uncovered a rather nasty security vulnerability that would have put all of our customers data at reach to anybody. I advised my manager, and was told - just ignore it and ship the code please. I refused.

I was threatened with being fired, verbally assaulted, and challenged at the most trivial ways in everything I did after that.

Jokes on him now. I work from home in my dream job, doing what I love, with a manager who actually gives a rats ass about my concerns.

Moral of the story here - you don't have to agree with your subordinates , but you do need to validate their concerns.
