Facebook tendered it's apology after an after an anonymous post from 12 employees under the group name "FB Blind" on online publishing platform The Medium went viral, USA Today reported on Friday.
"We may be smiling. We may post on Instagram with industry influencers and celebrities. We may use the IG 'Share Black Stories' filter and be featured on marketing pieces. We may embrace each other and share how happy we are to have the opportunity to work with a company that impacts nearly three billion people.
"On the inside, we are sad. Angry. Oppressed. Depressed. And treated every day through the micro and macro aggressions as if we do not belong here," wrote the Facebook employees.
The problem, they said is not just with black employees of different genders.
"The incidents are also reflective of behaviours against Latin and female Asian employees. The experiences invoke how we, the twelve Facebook employees present and past who are sharing our stories here anonymously, have been made to feel as employees by Facebook managers, HR business partners, and their immediate white colleagues," the post further read.
Hundreds of African-American Facebook employees embarked to Menlo Park, California this week to be part of its annual "Black" event.
"Many of us will go to the AfroTech event in Oakland to share stories, network, and meet up with other engineers, designers, and leaders in the industry," the employees wrote.
A company spokesperson told CNBC in a statement that no one at Facebook, or anywhere, should have to put up with this behaviour.
"We are sorry. It goes against everything that we stand for as a company. We're listening and working hard to do better,a said Bertie Thomson, Facebook's Vice President of Corporate Communications.
The employees wrote that "things have gotten worse since former staffer Mark Luckie published a note in November last year, claiming Facebook had "a black people problem."
"Racism, discrimination, bias, and aggression do not come from the big moments. It's in the small actions that mount up over time and build into a culture where we are only meant to be seen as quotas, but never heard, never acknowledged, never recognized, and never accepted.
"We are remaining anonymous because Facebook creates a hostile culture where anyone that is non-white is made to feel fear for their job and their safety to report any bad behaviours," they added.
