"I would first talk with my manager to make sure I understood the expectation correctly. It could be that I was interpreting it wrong or that there was some miscommunication. If I still had an issue, I would take some time to think about how I can deal with it. I've learned to pick my battles and to be adaptable as much as I can."

"I know well enough at this point in my career that policies and procedures are in place for a reason. If I truly don't understand the reasoning behind the policy, I will ask for further clarification in a respectful and open-minded way."
