I detest the picketers too. At some point they've got to realize (as common sense dictates) that they are losing in this fiasco more than anyone else.
So what's the store to do? When the strike is over, are they required to keep this woman in their employ even though she was arrested for attacking a customer? Suppose they keep her...should the customer avoid shopping there in the future as to avoid contact with the woman who assaulter her? I say a firing's in order.
