Nearly 200 business leaders on Monday endorsed an open letter on abortion rights, saying conservative efforts to restrict “comprehensive reproductive care” would be bad for both employees and customers. “Restricting access to comprehensive reproductive care, including abortion, threatens the health, independence and economic stability of our employees and customers,” said the open letter that appeared as an ad in the New York Times. Several prominent tech executives were among those who signed the letter, including Twitter chief executive Jack Dorsey, Jeremy Stoppelman of Yelp and Stewart Butterfield of Slack.
