Please stop with this nonsense you can 'work your way up' or that if only you work hard enough your efforts will be rewarded. That's long, long gone.
Companies don't care if you work hard or not. You're disposable to them. If you work hard, you only get given more work. By turning employment into "gig" work, they've shifted as much of the risk and costs onto workers, too.
Companies have weaponized employment practices and now they're just burning everything to the ground because they figure there will always be someone desperate enough. Turns out that doesn't quite work - Amazon for example has had internal memos circulating that say in various communities they're pissing off or injuring so many people they are having trouble finding workers.
"Gig" companies care so little, will suspend or cancel workers at the drop of a hat, intentionally or unintentionally. Even Uber's CEO, when he tried going 'undercover' as a driver to see what it was like, admitted he was scared he'd get a less than 5 star rating because it almost instantly torpedos you, especially if you're new. Because the "customer is always right", these companies offer no way to challenge a customer's complaint even if it's obvious nonsense. Why investigate anything, which costs money, if you've got a long line of people desperate to make $6 delivering a cheesebuger 5 miles?
Our legislators let silicon valley roll right over a century worth of worker protections because it was "innovative" (ie they got lots of lobbyist cash.) Voters let them do it because they want their delivered cheeseburger, groceries or makeup as cheap as possible....and voters don't care about the "losers" who work those jobs. It's not them, after all...
