In the United States, many social protections such as health insurance and unemployment benefits have traditionally been tied to an employment model that is changing rapidly. Work full-time at a white-collar job, and you will likely be offered health insurance, worker’s comp, and paid vacation (although there’s still no federal law mandating employers offer vacation to their employees). Work a part-time job or string together gigs through apps, as more Americans are doing, and there’s likely no safety net for you.
