violations of the psychological contract may be addressed through
Perceived psychological contract violation Both PPCV and perceived organizational support (POS) are based on the norm of reciprocity. Both POS and PPCV are types of social exchanges and therefore involve implicit obligations, rather than economic exchanges, which involve explicit obligations (Blau, 1964; Emerson, 1972).[4][5] Perceived organizational support is focused on favorable treatment and the degree to which employees engage in positive reciprocity with the organization, whereas PPCV is focused on unfavorable treatment and the degree to which employees engage in negative reciprocity with the organization.
