Alphabet, the parent company of Google, announced today it was cutting 12,000 jobs. CEO Sundar Pichai made the announcement in an email to Google employees. The news comes amid a wave of layoffs at large technology firms, including an announcement earlier this week by Microsoft Corp. that it would reduce employment by 10,000 jobs.

Google cited a changing landscape in making its cuts.

“Over the past two years we’ve seen periods of dramatic growth. To match and fuel that growth, we hired for a different economic reality than the one we face today,” Pichai wrote.

The cuts follow a review of roles at the search giant and the reductions cut across product areas, functions, levels and teams.

Google plans to offer departing US employees pay during the notification period (a minimum of 60 days); a severance package starting at 16 weeks’ salary plus two weeks for every additional year at Google; 2022 bonuses and remaining vacation time; and six months of healthcare, job placement services and immigration support. Outside the US, the company plans to support departing employees in line with local practices.

The Alphabet Workers Union, which seeks to represent both directly employed and contingent workers at Google, blasted the layoffs.

“While Alphabet leadership claims ‘full responsibility,’ that is little comfort for the 12,000 workers who are now without jobs,” the union tweeted. “This is unacceptable behavior for a company that made $17 billion in profits last quarter alone.”
