I think this reflects a general erosion of trust between employers and employees, which I blame Corporate America for. It used to be a tacit agreement in the workforce that if you worked hard, the boss and the company would take care of you. This illusion has been shattered first by the employers (outsourcing, at-will employment, gig economy), and now the employees (ghosting, switching firms without notice).
The lack of trust on both sides engenders the feeling that any promotion is unlikely and every position uncertain, so folks always have one foot out the door. Once the trust is gone, it takes a long time to rebuild, so even if corporations changed tack now, it's likely that employees will continue to distrust them for the foreseeable future.

Edit: Clarity.
