心理契約的變革要求我們對人力資源管理系統中某些與心理契約關系密切,同時隨著員工心理契約的變化難以有效發揮作用的部分進行變革,具體可以從以下幾個方面入手:建立心理契約動態追蹤測量制度以及時了解員工心理契約的變化特點;建立薪酬模式動態選擇機制以滿足員工對經濟利益的需求;進行職業生涯設計以滿足員工自我實現的需求;建立雙重公平體制以滿足員工對公平的追求;實行自我管理式學習以滿足員工對能力提高的需求;對員工進行心性開發以引導員工形成正確的心理契約。只有組織的管理者真正認識到心理契約的重要性,認識到心理契約對員工的態度和行為的影響,重視心理契約的建立和維護,才能在人力資源管理甚至整個組織管理中應用好心理契約這一劑良方。分享友人
