I think this is a new term: meaning to do the bare minimum at work, while looking for another job.
I'm not a fan of quiet quitting...especially since it dumps work on the next person and as a child of a Chinese immigrant family I was always taught about the importance of work and education. Mind you, it doesn't mean I won't be proactive or direct.
Apparently, there's quiet firing (avoid pay raises and promotions until workers quit) and quiet dumping too. I wonder what the advantages and disadvantages there are compared to straight ghosting, quitting, or firing.
