If there are not enough jobs in the area and not enough capital to kickstart businesses, the people in that area are in a situation where something is better than nothing. So a corporation can come in, offer below subsistence wages and the people will feel as if they have no other option. It's not what the labor is technically worth because the value produced by the labor far exceeds the wage given to the laborer.
Individual laborers have no power to fix this. The employer can fire them and exploit the next desperate person. They can even cycle through back to the original person as they get more desperate.
Collectively, the laborers can do something. They can redress the balance between laborer and owner. But only as a collective. The minute the individuals are allowed to operate independently, the old system reasserts itself.
Stop carrying water for people who won't even allow you a drink for your efforts.
Because they are employees. if enough employees of any organisation stop working, the organisation shuts down.
And whether you like them or not, they provide a feedback loop. Otherwise bad organisations whither away as good workers leave and bad workers stay.
