I have encountered a frustating situation in my current job that I have never encountered before. Looking for any advice anyone can offer.
I work with multiple teams to coordinate and manage schedules. This requires me to coordinate across many teams on deliveries and a workplan.
I have one team who consistently comes back after the fact and denies agreeing to dates/projects. I document every meeting and share the meeting minutes/agreements with all of the participants.
In spite of this I am sitting again today in a meeting with this team saying they never agreed to the plan and in fact were never in the meeting. They are getting in front of executives and basically accusing me of being a liar or of not communicating appropriately.
I have had others corroborate my version of events on some of these occasions including the latest. I have produced the meeting notes/agreements to back up my point. This is ignored by these people. They do not acknowledge it.
I am stuck on how to have a meaningful working arrangement with these people and how I can count on any agreement with them holding.
I don't want to be in this position again. I feel it is damaging my reputation.
