ELI5: Why are all of the Walmart employees going on strike?

I understand that it's very low paying. But then why not just quit and find another job?

1. The economy doesn't work like that. There aren't a lot of jobs in a lot of places. Unemployment may be back to relatively close to pre-2007 but the jobs that have been coming back have been created have overwhelmingly been low wage jobs. Throw onto that the fact that they put many small businesses out of business since they can't compete with the prices at Walmart, and Walmart can only sell at those prices by paying poverty wages at nearly every level of their operation. 

2. Why not? Somebody has to stand up to Walmart, and politicians won't. All Walmart cares about is making money, and they don't make money if workers don't work. They are using collective action to make Walmart listen and respect their right to form a union. Walmart pretty much by policy violates labor laws every day by firing pro-union workers, telling employees not to talk about how much they make, and even making people work off the clock. 

3. Service work us the new bedrock of our economy. You can't outsource it. It's here to stay. We can decide to make those jobs good middle class jobs. You probably think of jobs in manufacturing as solid middle class jobs. Well, until workers in the 20s and 30s started striking in the steel mills, paper mills, etc., those jobs were the worst, most dangerous, lowest paying jobs around. But those workers fought to form unions, make their voices heaed, and made a whole new class of middle class jobs that led to the great expansion of the middle class in the 50s and 60s. We have the opportunity to make that choice now. And right now, wealth inequality is at levels we haven't seen since 1929, so it seems like as good a time as ever.
