Whats your solution though? Strike? People will still apply and work there because it's bad, but not slave labour. Unionize? They'll entirely stop hiring people without experience and change their business model.
Their business model was to be the cheapest. Cheapest employees, cheapest parts. They filled the market share for people looking for cheap cheap parts. That involves crappy service.
If they raised their employee pay, the entire business model goes belly up. That means, no more cheap cheap parts for customers and no entry job positions for employees looking to break the field.
It was a delicate balance of ""exploitation"" and keeping them happy enough they are willing to stay.
If you have nothing to offer the company besides a pulse, you don't get to pick and choose. Why would that be fair to force a company to pay more for no reason? Sometimes you put up with bullshit for a couple years and then you get to be more picky.
