The psychological contract refers to the unspoken mutual understanding between an employer and employee that is not explicitly stated in a formal agreement. It encompasses the individual's personality, approach to achieving business goals, and perception of their role within the organization. The psychological contract can be both beneficial and detrimental, as it can foster loyalty and commitment or lead to feelings of betrayal and disengagement if breached. Effective communication is crucial in managing the psychological contract, and managers must be aware of the potential for ambiguity and misunderstandings. Breaches of the psychological contract can have significant consequences, including damage to employee-employer relationships and reduced productivity.
