Thousands of Google contract workers responsible for training and rating the engine’s search results will receive a historic pay raise this year after a months-long Alphabet Workers Union-CWA campaign, the AWU-CWA announced Wednesday.

The workers are based at RaterLabs, an AI training vendor whose only known client is Google, according to an AWU-CWA press release. Where these workers, known as raters, were previously paid as little as $10 an hour, they will now be paid $14 or $14.50 an hour, depending on experience. The AWU-CWA estimates that the raise will affect between 3,000 and 5,000 workers, for a total collective salary increase of about $10 million.
