The Office of Special Counsel has said that now that the elections have passed, it is okay for federal employees to literally wear their politics on their sleeves by wearing candidate-oriented t-shirts and similar clothing in the workplace.
A Hatch Act interpretation issued by the office notes that the law bars engaging in political activity while on duty, in uniform or in the federal workplace, and that political activity is defined as activity directed toward the success or failure of a political party, candidate for a partisan office or partisan political group.
It noted that technically speaking, the Presidential election will not be over until January 6, when the Electoral College finalizes the results of the voting, but that "we do not believe that wearing their campaign t-shirts or displaying their pictures after Election Day is activity directed at the success of their candidacies. Accordingly, the Hatch Act does not prohibit a federal employee from doing so, even while on duty or in the federal workplace."
