I don't think people are paying attention to what's happening. They just hear "wage increase" and yell "yaaaaaaaay".
Companies starting paying more when they needed less people. I can now order my food on an app and it's ready when I get there. No need for cashiers. I can even have somebody walk it to my car. In the restaurant the person at the counter tells me to use the kiosk. If the ease of this isn't incentive enough, I get coupons and free stuff for bypassing in person ordering. Now, the restaurant pays 2 people 15/hr instead of paying 4 people 8/hr.
Supermarkets are no different. They have self checkout set up.. One cashier open and 10 self checkout lanes. You get accustomed to doing it yourself because nobody wants to stand on a line for 20 minutes if they don't have to.
Sure the companies will play ball while they have to, but they're getting rid of the jobs they don't need. The more employees cost them, the more they're faster they're looking to automate jobs and get rid of them. Consumers become accustomed to because they're offered free stuff and convenience.
Start all the unions you want. It doesn't change the fact that this country (if not the world) is run by big tech, big pharma, big retail, big banks and the military industrial complex. Nobody cares about little employees unionizing. They'll tolerate for now, but they shrinking their staff and doing it fast. What good is it to be an unemployed union member?
