Can you imagine that they pay$300 per month (gross) to cashiers here? Consider that food and apartment prices in my country are more expensive than in most of European countries, this is crazy.
Look, I'm in the EU and the average salary in the net amount for an employee in a store is from EUR 750 to EUR 950, which is somehow the legal minimum wage. Of course, there are exceptions where people are paid more, but from what I've seen in such stores, you work like a machine in every possible position and people are under a lot of stress.
Btw I agree with your mentality, in situations like this, it's our duty to stick our nose there but the problem is the mentality of my people. If you protest low salaries, another one will come who will work on lower salary. There have been multiple protests but all of them have failed because there is always somebody who is willing to work for a lower salary despite the fact that this salary is not enough to live.
It's not just a problem of the mentality of people in your country, I think it's the same everywhere in the world - it's more a matter of a collective consciousness that this is a job that anyone can do and that therefore people who work there can be paid very little for their work. Where I live, teachers, doctors and various civil servants often go on strike and demand higher wages - and at the same time they have at least 50% higher wages than those who work in supermarkets - in other words, life is hard for them, but they don't care about those who are exploited by the private sector.
