Progressive discipline is a disciplinary model in which the severity of the punishment increases each time an employee commits an infraction.
Generally, the progressive discipline scale starts with an oral reprimand, followed by a written warning, suspension, and finally, termination. Progressive discipline procedures are most often found in collective bargaining agreements and in the public employment arena, but are also common in the private sector.
There are two potential problems with having a progressive discipline procedure in an "at-will" relationship. First, it can be time-consuming to administer the steps and generate the accompanying paperwork. Second, a progressive discipline procedure can, under certain circumstances, change an at-will employment relationship to a contractual one.
