re: Is a large part of working in IT just playing the blame game?

Where I work, I see the entire I.T. department play 'hot potato' with the service tickets all day, every day. Every one of them find some random scenario that would make it not their fault and they pass the ticket to someone else. After it makes it rounds back to service desk, they'll basically have to write up a goddamn legal brief in order to get the other team to actually consider that it may be something in their scope. Under no circumstance will they actually contact the user to see if what they are suggesting may be on their end. It really gets ridiculous at times because the I.T. department is global so none of the teams actually have an type of relationship with each other. Working as a team on a solution is out of the question.
