Iterative changes and discussion about submission deadline

I was assigned to work with the most annoying on-site team lead by my manager and adding to this issue my manager himself has nominated for the support. Most annoying part of working on this opportunity was getting insights from my manager, as he always provides unnecessary and irrelevant changes for the storyline, which would be thrown out by the onsite team. At many times, I sense that even the onsite team wants to keep out my manager for updates and my manager would be left out on purpose in mail threads. So, for this opportunity the onsite team was looking for customization specific to client requirements and my manager was completely against it and was suggesting alternative slide on every call. The most irritating part of it is that, I had to exhaust all my effort for that one slide suggested by my manager and at end of the day it would be trashed out by the onsite team. This was continuing on for a while and out of curiosity I was checking with my manager for completion date and my manager was mentioning that the opportunity would be completed by this week. I was wondering about the submission response, as with multiple iterative changes, it would take one more week to complete the document and I wanted my manager to validate the submission with the onsite team. However, the response shattered my handwork and to know more, please feel free to check out the blog posts in “G R Team Sites”
