>Most people can't just "unilaterally rescind" their employment if they decide they don't like it anymore.

I suspect what's meant here is that most anyone can take a different job and leave one that no longer serves them, not that most anyone can walk away from a job without another lined up.

I agree, and also, if it becomes not beneficial to me (for instance, large increase in responsibility for no raise), I will move from "do my absolute best mode" to "minimum effort mode" until I can line up something else -- which is just me realigning my effort level to match the standard set by the Company.
