The framing of "quiet quitting" as a problem says more about employer expectations than employee behavior. You're not quitting. You're working exactly as hard as your compensation and job description warrant. The expectation that employees should give maximum effort at every moment, on top of stated obligations, is the unstated contract most employers try to enforce.
The real tension is this: companies want an emotional investment that can't be negotiated in a contract. They want commitment, loyalty, passion. But those aren't commodities you can demand. You can demand hours. You can demand task completion. You can't demand enthusiasm without paying for it somehow.
Some jobs are designed well enough that good work *is* naturally engaging. Most aren't. Most are designed around extracting maximum output for minimum cost, then acting surprised when employees protect their mental energy.
Quiet quitting isn't the problem. It's evidence the employment relationship has broken. The employee stopped pretending they care more than the paycheck justifies. That's honest, not selfish. What looks like underperformance is usually people finally performing at the level the job actually deserves.
