　　“自愿降薪”四字一出，众多网友表示：“公司效益良好，所以员工自愿降薪，这个逻辑过于离谱。”就该公司说法来看，员工自愿降薪是对其忠诚度的测试，也是非常好的共渡疫情的模式，而且降低月薪的同时实际上提高了年终奖。然而，该说法本身就很吊诡。如果提高的年终奖难以弥补员工所降之薪，那么实际上还是降薪，所谓提高了年终奖只不过是个美丽的误会。如果提高的年终奖幅度超过了员工所降之薪，那么又何必多此一举，来个先降后涨？

　　而且，员工工作本就是为了实现自我价值的同时获得自己应得利益，尽管在疫情期间存在部分公司通过降薪以共渡难关的案例，但也不能以忠诚度测试为由模糊“公司效益良好，允许员工自愿降薪”一行为对员工的侵犯，让员工陷入自愿降薪利益受损，不自愿降薪可能面临其他刁难的困境。
