Netflix had the largest share of happy employees in the US in 2019, a survey by the anonymous-professional-networking app, Blind, found. Blind, which requires a work-email address to verify employment at a company, surveyed more than 10,000 of its 3 million users in the US during the month of December, to see how happy they were in their workplaces, and whether they felt they had grown in their careers in the last year.
