CHARLOTTESVILLE, Va. (CBS19 NEWS) -- Thousands of Uber and Lyft drivers across the country went on strike on Valentine's Day, calling for higher pay and other changes to their working conditions.

Drivers planned daylong strikes in cities like Chicago, Philadelphia and Miami.

Paolo Fridman is a local driver for Lyft and Doordash, a service similar to Uber Eats.

He drives for extra cash but says he knows people who do it for a living, many of whom he met driving in his hometown of Chicago before moving to Charlottesville.

Fridman says he'd never be able to live off what he makes from driving and delivering food.

When driving in Chicago, he made friends with some of the other drivers in the city; many are immigrants looking for work who do it as a full-time job.

Fridman tells me drivers need to plan their day around the busiest hours in order to make the amount of money they need.

"If you live in a college town like Charlottesville, a lot of kids are coming home to the bars at 1, 2, 3 a.m., what are they doing? They're ordering food. So, you have to be working when there's demand, and if you don't, you're not going to make any money. I've spent plenty of hours waiting and waiting for orders them never to come," he said.

He says it can sometimes take eight to ten hours to reach just $100.

Drivers were also holding demonstrations at airports in cities, according to Justice for App Workers, the group organizing the effort.
