Google says it will require staffing companies it works with to pay workers at least $15 an hour and give them health benefits.
The company has faced pushback from employees and contract workers for paying contractors less than full-time employees.
Google did not say how many contractors and temporary workers it has, but reports say it is many thousands of people.
Google's new rules will require contractors, who are usually employed by third-party companies, to also get 12 weeks of paid parental leave and a tuition reimbursement each year for classes.
Contract workforces are common in the tech industry and often get paid less and have fewer perks than full-time employees working for tech giants.
