Why would anyone do that?

How would that work? Am I taking a vacation day from my corporate job so I can make $12/hr bussing tables? I’m not sure why I’d ever want to do that.

What would happen is this app would just turn into another form of gig work for unemployed people, and it would be a nightmare. Imagine going to a restaurant and no one knows what they’re doing, because they’re only there for a day. The restaurant would probably lose money due to waste and the bad reputation.

No. I got into corporate work to get away from the hell that is restaurant/retail work.

It would be cool to do some evening shifts at a restaurant, for the novelty and the social aspect (compared with staring at a screen all day)... plus the work is cognitively very simplistic... quite relaxing compared to corporate life. The problem is, if I have a day job as an engineer, my regular income puts me in a high tax bracket. So, not only would I be earning close to minimum wage, I would be taxed at the highest tax rate on the minimum wage... so it really would be a waste of time. Progressive tax rates are what makes it unviable for high income earners to pick up a weekend or evening job.

They're struggling with employee turnover because the boss won't pay competitive wages. Why won't the boss pay competitive wages? I have some ideas, but rather than project I'll just say that's the problem to solve.
