I would presume it would work the same as if you had two other part-time jobs, such as working at both Walmart and Best Buy.

It's different though. Part-time retail workers pledge their loyalty to Walmart from 9-13 and to Best Buy from 18-22. They're not instantly choosing which boss is paying better for the next 15 mins. You actually have to get someone to cover your shift if you need a mental health break or something -- otherwise, your relationship with Bestmart is strained and you might be out of work.

For all of the phoniness behind phrases like "ride-sharing" and "gig economy", workers have never had a more horizontal relationship with their bosses -- except, perhaps, in higher pay-grade service sectors where "bosses" are referred to as "clients".

It's extremely common to not have fixed shifts. You ask for hours, and you get what you get. It's really not that different from accepting individual driving jobs.

There is also a dynamic where you are assigned shifts and if you don't make it your fired. Gets pretty dicy when you have two of them.

But neither company would pay you as a full time employee when you're jumping between jobs for both in the same hour/shift.

But if you are part-time, then you don't get employment benefits.

That's an interesting conundrum. I don't think Uber or Lyft has it in their terms that they forbid it. At the same time, they don't seem to compete enough on worker rights and pay either, so for the drivers it's not beneficial to go exclusive.
