Everyone worries about catching a cold at the office, but if you’ve got a mean co-worker you might also be in danger of catching their rudeness, according to new research from the Journal of Applied Psychology.

To reach their findings, researchers from the University of Florida tracked 90 graduate business school students practicing negotiation techniques with classmates, with each person practicing with multiple partners over 7 weeks. In the end, they found that those who rated their partner as rude were far more likely to be judged as rude themselves by a subsequent partner.
