Some Big Law firms are giving employees a day off Friday, June 18, in observance of Juneteenth, which falls on a Saturday this year, and are encouraging their staff and attorneys to volunteer and take up pro bono work on the holiday.

At least nine law firms have enshrined Juneteenth, the anniversary of the liberation of the last group of enslaved Black Americans in the Confederacy, as a permanent paid holiday going forward. Dozens of law firms observed Juneteenth last year—less than a month after George Floyd’s murder, which sparked increased conversation about systemic racism in the United States.
