I stopped saying No. If management wants to push stupid decisions, so be it. They are getting payed for strategic decisions. If their strategy is bullshit, so be it. If they tank the company, so be it. I am not getting payed for that kind of work. And the more bullshit I hear from upper levels, the less I identify with my company.

What if management pushes stupid decisions and blames you for the second order effects? Happens often.
