In some organizations, chronically resistant employees occur, who will consistently resist any change initiatives. These employees are afraid of change, attacking all things that are outside their comfort.
Toxic employees use social hacking to manipulate others using rumors, silent treatment and intimidation. These employees need the environment not to change so they can hold onto their informal power.
If no other employees on the team behave in this manner, then it is clear the employee does not fit well with the organization. If they are a valuable worker, the organization may attempt to find them work in a different area of the organization that could perhaps fit the personalities of the employee, creating a beneficial scenario as the employee is removed from their current toxic role and can still add value to the organization. All employees have unique personalities, values and needs and may benefit in different job roles.
