The word "toxic" has lost all meaning these days. It would be interesting to see some actual examples. I've worked with people, in the past, who would be considered "toxic" by today's standards. For example, they were disagreeable, pointing out when time was being wasted on tangents, demanding data to back up claims, and all those other nasty things that help keep a team truthful and on track. They were great to work for, if you could stomach criticism and directness, which seems to be getting rare.
