A restaurant can get away with giving everyone crappy part time work IF the restaurant knows that on demand it can request people to work more hours/extra days.

A restaurant can get away with giving everyone crappy part time work IF the restaurant knows that on demand it can request people to work more hours/extra days. It sounds like an efficient way to run in a grad school sense. But what happens when people start saying no or get sick? The restaurant is closed at odd times, people are inconvenienced and just start going somewhere else, has opportunity costs because it has to pass on that last minute phone in order from an office catering lunch because it's minimally staffed (to be market efficient). Cutting to absolute minimum viable is a horrific concept if you are building a business. You lose your best people, you have a ton of opportunity costs, and you basically give up on growth, productivity goes down as your remaining people have to do way more context switching. If you are running a zombie company and just squeezing the last bits out it might be considered running a business I guess?
