Tweet

in our company, we had one admin managers meeting after three months interval or sometime more. We have 11 projects overall. And one admin manager attend the meeting on behalf of project. I just today got an invitation for meeting with very boring agenda as usual. Its more sort of fight meeting, blaming each others on number of things, complaining from top management, complaints from team members etc, new policies with no such difference. I really dont wantt to attend but i know how important this is for me to attend. What should i do? any good suggestion please
