Toxic behaviours are acts that poison the work atmosphere. They grow from selfishness and insensitivity and go from mockery to manipulation.
Toxic behaviour is destabilizing, generates stress and frustration and has a negative emotional impact. It steals your energy.
If you can’t limit or cut-off contact, Robin Stern, associate director of Yale Center for Emotional intelligence suggests shielding yourself by setting firm boundaries. Assertively say no to demands that feel unreasonable - without justifying yourself.
