The Psychological Contract defined

The concept of psychological contract was first put forward by Argyris(1960), a famous American behavioral scientist, he talked about the hidden and informal unspoken agreement between the foreman and workers. Argyris just proposed the conception, but no more specific definition (Argyris, 1960). Then analyzing information from the face to face talk with 847 employees in a case study in a public institution Levinson defined psychological contract as unwritten contract that literally means a mental contract between employer and employees without letter contained expectations (Levinson et., 1962). Later Guest theorized that, psychological contract is concerned with: "The perceptions of both parties to the employment relationship, organization and individual, of the reciprocal promises and obligations implied in that relationship" (Guest 2007, PP 22-39).

The key developments leading to its current use as an analytical framework were provided mainly by Schein(1965), He explained that The notation of a psychological contract implies that there is an unwritten set of expectations operating at all times between every member of an organization  and the various mangers and others in that organization (Schein 1965).

This definition was amplified by Rousseau(1994) as Psychological contracts refer to beliefs that individuals hold regarding promises made, accepted and relied upon between themselves and another. (In the case of organizations, these parties include an employee, client, manager, and/ or organization as a whole.) Because psychological contracts represent how people interpret promises and commitments, both parties in the same employment relationship (employer and employee) can have different views regarding specific terms (Robinson, Kraatz, & Rosseau, 1994).

This conception was further identified by Morrison(1997). He pointed out that the psychological contract was usually defined as a set of faiths was held by employees about mutual responsibilities. These faiths were based on making sense of promise, while they might not be known by the organization or its agent (Morrison & Robinson, 1997).
