California has passed a bill that classifies gig economy workers as employees, which is expected to be signed into law and take effect next year. The law may have significant implications for companies like Uber, Lyft, and Doordash, which have already begun a $90 million ballot prop campaign to exempt them from the law. The bill's impact on the gig economy and workers' rights is a subject of debate. The law's effects on the companies' business models and profitability are also being discussed.
