These people drive me up the wall….
Example, you all sit down to hear about a new project, and as the scenario is explained, these people will interrupt or make it their mission to raise red flags “I think X might happen which would be really bad” or “this specific thing could be really difficult”.
They imagine that they are being wise contributors to the process, but in reality they are just fountains of negativity. They are never the most productive, they rarely take on the hard stuff because they are afraid, and at worst they shove off work to others having already demonstrated their value proposition by merely shouting about a potential risk that may not may not come to be.
A Red Flagger is usually accompanied by other symptoms such as: brown nose, work avoidance, or easily overwhelmed.
