A printing company in Maryland saw the photo on Twitter Wednesday night: an employee roaming the halls of the US Capitol with a company badge around his neck. He was fired the next day.
Others are facing similar repercussions for their participation in Wednesday's riot at the US Capitol.
Some business owners are being trashed on social media and their establishments boycotted, while rank-and-file employees at other businesses have been fired.
The printing company, Navistar Direct Marketing, declined to name the worker but said it can't offer employment to people "demonstrating dangerous conduct that endangers the health and safety of others".
More than 90 people have been arrested since Wednesday when loyalists to outgoing President Donald Trump disrupted lawmakers as they met to confirm the Electoral College results and President-elect Joe Biden's victory.
People on social media have been trying to identify rioters photographed or filmed at the Capitol Wednesday, pressuring companies to fire those employees.
At a data analytics firm in suburban Chicago, the employee in question was the top boss.
Cogensia placed CEO Bradley Rukstales on a leave of absence for participating in the riot and said his views don't represent the views of the company. Rukstales, who was arrested for unlawful entry, told a local CBS news channel that he had entered the Capitol and apologised for his role in the events. Calls and emails to Rukstales weren't returned.
A Cleveland school occupational therapist resigned from the district after her alleged involvement in the riot. A spokeswoman for a fire department near Orlando, Florida said one of its firefighters was being investigated for his participation. Sanford Fire Department firefighter Andy Williams has been placed on paid administrative leave pending the outcome, said spokeswoman Bianca Gillett.
