One of the things I do is manage an enterprise support relationship with one of our vendors. We pay them a big sum of money, and in return we get access to a variety of support resources, including some guys who come in and help us out for a limited number of days. The latter are contracted by the vendor to provide support.
A couple of months ago, I had a couple of projects going. I talked to the vendor about one, and to the contractor about the other. Ultimately, we later learned that the second impacted the first. Unfortunately, neither party brought it up, and after completing the second project, we found that in order for the first to be completed, we would have to redo the second. This was all completed using days on that contract.
So, I'm asking for my days back. I've gone back through emails, stamped my feet, and said, basically, give me back my days, or I'll find someone else and next year, we won't use their services. But now the vendor is going back to the contractor and pressing them to cough up the days. I shouldn't care, but I do, because the contractor is who I work with regularly, and I also think that the communication and management is the vendor's responsibility.
So, now there's this tension as I go about my business. I don't doubt my position, but I need the help to get this all sorted before I can go any further.
