Why do users hit me up on teams to ask me to help them with something, and when I ask if they are available for me to stop by, they ignore me? Then I go on about my day, and my manager comes to me later saying they complained that I never showed up to help them. Am I missing some unspoken rule of modern american office culture?
Ticket or email. Any kind of written proof is good. If people complain you can show that no detail has ever been given.
It works too when people try to fire you without a valid reason but that’s another story.
