I noticed different strategies.
Mark always brings up difficulties with his children to avoid calls and tasks.
John simulate that his tasks are very very difficult. They are very simple and quick to do, but manager doesn't know.
Luke is my favourite. He is always overtalking. No one can handle its loooong recap of what has done and have to do. Manager just want him to end the conversation and never ask him about anything else
Sometimes I wonder if managers can't see these patterns lol
