“It happened again. Nicholas Pilapil got an email clearly meant for his co-worker, Jonathan Castanien. Previously, Pilapil had missed a meeting invitation because their white co-workers couldn’t tell them apart.

So they came up with a cheeky way to address the problem. Between their desks, Pilapil and Castanien hung a sign that read, “This company has worked __ days without an incident. Incorrect names are avoidable.”

Whenever a co-worker called one by the other’s name, they would reset the count to zero. During the six months or so that the sign was up, the count never exceeded 14 days, Pilapil said. In total, they were misidentified about 50 times.”
