We've all worked on dysfunctional teams at times, and we've likely been part of the problem too. A dysfunctional team creates a lot of angst and havoc. What can you do in situations like this.
First, of course, you can try to redirect and fix the team via your own efforts.
Next, if your efforts to make the team work better don't work, you have decisions to make including will you stay on the team, and if you stay on the team, what will your role be--how will you still do good work despite the team's dysfunction/
After that, it''s best to do the good work possible and distance yourself as much as possible from the negative aspects of the teamwork. This may be a time when you begin to create a new team that supports the vision you have.
Dysfunctional teams will happen for all kinds of reasons. Often these teams are the result of no one's fault, but instead, circumstances that arise.
In the best of circumstances, we should strive to be the best possible team members as well as promoting the best possible teamwork. Yet, when that doesn't happen, we have to change our expectations and find another way. Onward.
