Manager keeps expanding the dev plan and rejecting to put on pivot
It's been 6 months, he doesn't count some of the work (he himself assigned to me) in the dev plan, and doesn't clear me out of it. I asked him to put me on pivot, but he doesn't do that either. He just keeps extending the plan. I'm mentally tired. He's full of lies and I don't trust him at all. Even when I confront him for a lie, he just says "I don't want to answer this question".
What should I do to force him put me on pivot?
