Facebook owner Meta has told staff they are banned from talking about abortion on the company's internal discussion boards over fears of becoming a "hostile work environment".
Employees of Meta, which also owns Instagram, are not permitted to post about abortion on the company's Workplace tool, a Facebook-style website intended for internal communications.
Janele Gale, human resources vice-president, told staff that abortion was "the most divisive and reported topic" on Workplace, according to tech website The Verge.
Gale reportedly said "even if people are respectful, and they're attempting to be respectful about their view on abortion, it can still leave people feeling like they're being targeted based on their gender or religion".
The site reported other internal Facebook directives from early May suggesting abortion could only be discussed in groups of no more than five people.
