It’s also a respect shortage, and a flexibility shortage, and a plannable scheduling shortage.
Nowadays I try and be extremely polite to people serving me food or checking me out at the grocery store, and make a point to only be mean to people whose job it is to be yelled at.
I'm not saying you get personal and insult their mothers or anything, but being impolite and slightly aggressive is (sadly) sometimes necessary.
To be clear, I'm suggesting someone filter through the fiction and hyperbole and identify real cases of unfair working conditions and tell those true stories in a documentary. Filtering out the hyperbole is an important part, people need to be able to point to the documentary as a source of documented unjust treatment, something more reliable than Reddit.
