Here is another situation that I call Project Stealing.
4 of us are working on a project that is semi-important. My goal is to do an analysis, kill the issues, and get on to more important work. One of the project members, let's call her Suzy Q, has other intentions.
Suzy Q greatly exagerates the issues we identify and turns the proverbial molehill into a mountain. Ends up with our Manager getting worked up and taking it to the Corpoarte Board.
Next Suzy Q seeks total control of the project. She accomplishes this by setting up Project Meetings and sending out double invitations. In other words she'll send out 1 set of invitations to the other 3 employees working on the project, and a second set of invitations to High Level Managers (who are all in a frizzy) who appear at the last part of the meeting, which can be really confusing since nobody else expects Board Member X to show up. Another tactic is the last minute meeting invitation. Where she schedules a meeting with High Level Managers and then 1 hour before the meeting Suzy Q invites the rest of us -- who are really unprepared -- to show up. It's not like you can't show, when your Manager and 2nd Level boss are there. This allows her to dominate the agenda, she looks like the only one who cares about the project and is asked to lead the project. Lots of credit stealing that Willie Wannabe described is also going on.
This project is a mess. Lots of political implications since Suzy Q has stirred the pot into a boil and the issues implicate a different work group.
My solution was to get the the hell out.
