All the methodologies I was forced to work on basically didn't work, all the methodologies are just a play of “business theater”.
Someone with the power to decide decides to use anything fashionable, now it's Scrum, but it used to be something else. Whoever does well in this theater isn't a good employee, it's whoever does best in the current play.
My defense in the face of all this nonsense is to be professional, because the company will never be. I start work on time, do my work, leave on time. I help in emergencies, but if emergencies become the norm, I change sectors, hours or companies.
I try to avoid meetings. I say “I’m working on something important.” Always works.
I never allow anyone to disrespect me (I know a company with “physical punishments”). If that happens, I'll change companies.
Again, Scrum is not the problem. The next fantastic methodology will fail. It's just a Play, and you need to be an actor, or move to a theater whose play is in pre-production...and enjoy it until the play starts to be performed.
