Recruit Holdings, the Japanese parent of Indeed and Glassdoor, said on Friday that it is laying off about 1,300 employees, or 6% of the staff, at the two job sites.

The job cuts would affect functions mostly in the U.S. across the two companies’ R&D, tech, and HR and sustainability divisions, Reuters reported, citing an internal memo.

Reuters also reported that the company’s CEO, Hisayuki Idekoba, wrote in the memo: “AI is changing the world, and we must adapt by ensuring our product delivers truly great experiences for job seekers and employers.”

Glassdoor’s operations are also being integrated into Indeed, Reuters reported, adding that Glassdoor’s CEO Christian Sutherland-Wong would leave the company on October 1.

The job cuts come as tech companies across the world roll back their sustainability initiatives and cut jobs to balance out extensive spending on integrating AI into their businesses. Tens of thousands of people stand to lose jobs at Microsoft, TikTok, Match, Intel and Meta, per announcements in just the past couple of months.

Indeed and Glassdoor did not immediately return requests for comment outside regular business hours.
