Does an implied covenant of good faith and fair dealing between an employer and employee constitute a tortious cause of action?

We do not hold that in each and every contractual arrangement between employer and employee, an implied covenant of good faith and fair dealing arises the breach of which gives rise to a tortious cause of [126 Cal.App.3d 427] action. We do hold that where the relationship of employer-employee has "matured into that of pensioner and administrators," then the "courts must be vigilant in protecting the rights of the pensioner against powerful ... administrators" and a fiduciary duty of good faith and fair dealing is owed (Symington v. City of Albany (1971) 5 Cal.3d 23, 33, 95 Cal.Rptr. 206, 485 P.2d 270), the breach of which gives rise to a tortious cause of action of the breach of implied covenant of good faith and fair dealing, for which a wronged party may recover all damages proximately caused thereby, including punitive damages in a proper case.
