Google promised not to silence workers who talk about their pay, part of a settlement resolving one of the first legal complaints filed by a new union representing hundreds of employees and contract workers at the internet giant.

“WE WILL NOT tell you that you cannot discuss policies with other employees,” states the notice to staff, signed by an attorney for Google and parent Alphabet Inc. and being posted at a Google data center in South Carolina. “WE WILL NOT discipline you because you exercise your right to discuss wage rates, bonuses, hours and working conditions with other employees.”
