> They're upset about sometimes getting trips from uberx (and apparently making more doing so), so they're going to a place that pays less per trip and per hour? They're trying to convince Uber to stop doing what they don't want (according to them, they do not make more by accepting UberX fares, no matter what the company says) by denying them labour. In the meantime, they're doing work elsewhere, although are hoping not to permanently work there; they're hoping that Uber will cave in. Denial of labour ("striking") is a tried-and-tested approach to persuading companies to do what the labourers want. They can't operate without labour, so labourers organise to deny them that until they get better working conditions/better pay/etc. Assuming enough labourers agree to deny labour, this will work unless (a) what the labourers want, the company literally cannot provide without going bust, or (b) there are enough people looking for jobs and willing to put up with the bad terms that the company can hire them to replace the striking labourers. This is a relatively simple idea, and has been a thing since the Industrial Revolution; I'm not really sure what you're not getting.
