How workers are using globalization against Walmart

I found an interesting article in Waging Nonviolence, a website for people to put up articles  "a source for original news and analysis about struggles for justice and peace around the globe". In this website the article of workers in walmart taking advantage of globalization against Walmart. 

The article writes that low skilled employees started a rampage "wildcat" of strikes at certain levels of the supply chain in order to show that they would like something more than just a low pay and get better working conditions. These wildcat strikes had affected Walmart's delivery datelines due to the accurate hit of the strike. Walmart is not a production company but a selling one. Hence it relies on daily deliveries to different  venues at certain times and at the right price. When these timings are not met, it affects their reputation as well as their profits. 
This article shows that even though workers at walmart are low-skilled and lowly educated, they still have the brains to use their work venue as their advantage to get what they want. 
 The warehouse at Elwood located at the outskirt of Chicago, is a prime example of these workers using it as their vantage point. Elwood area processes 70 percent of Walmart's domestic goods. In this area, there are warehouses, distribution centres,container storage locations and intermodel facilities that are all vital to the production and deliveries of Walmart's goods. If one of these facilities were to stall, Walmart's production system would be deeply affected, as transportation is the crucial role here.
When workers in Elwood went on strike, it affected Walmart badly, since then, when workers asked for safety equipment, they were given. In addition, they were given full back-pay. The managers were more afraid of the workers than the workers of them.
This article shows that globalization has turned the tables on managers. Despite being on the losing end for unions, they still can find a way to come back and show that workers have the power as well, when they strike at the right point.
