“Stories of people who ruin things for everyone else…or who are accused of that. [..] A bad apple, at least at work, can spoil the whole barrel. And there’s research to prove it. Host Ira Glass talks to Will Felps, a professor at Rotterdam School of Management in the Netherlands, who designed an experiment to see what happens when a bad worker joins a team. Felps divided people into small groups and gave them a task. One member of the group would be an actor, acting either like a jerk, a slacker or a depressive. And within 45 minutes, the rest of the group started behaving like the bad apple.”
