58% of businesses say they’ll prioritize AI proficiency and understanding when hiring freelancers in the next three months4
Upwork, the world’s human and AI-powered work marketplace, released its Monthly Hiring Report for September, revealing rising demand for skills that combat AI “workslop,” such as quality assurance and project management. The report illuminates real-time trends signaling how business leaders are hiring, providing a more comprehensive picture of the U.S. labor market by focusing on the freelance economy – a dynamic sector of the workforce that generates an estimated $1.5 trillion in annual earnings.1 It draws upon data from more than 1 million job posts in the U.S. on Upwork’s marketplace annually and a monthly business pulse survey from the Upwork Research Institute.
“Our real-time platform data gives us a unique view into what companies are hiring for, what skills are rising, and how work is evolving in the age of AI, which is changing and enabling new types of work in virtually every category,” said Erica Gessert, chief financial officer at Upwork. “The trends in this month’s report underscore the powerful truth that the future of work is human-AI collaboration, not substitution. From quality assurance to translation, human involvement is essential to turn AI’s potential into quality outcomes and actual business value. Companies are hiring for these and other uniquely human skills to ensure their AI investments pay off.”
