Who cares if they take a knee, but doing it on "company time" and insulting something almost sacred as our country's flag is wrong.  An example: if people who used to work for me would have stood on the front porch of one of my customers, with political sign opposite of that customer's, just to make "a stand" I would have fired them no mater how good they were at their job. Let them put their money, or can I say Big Money to work for their stand.
