On Thursday, the Governor of Pennsylvania, Tom Wolf, signed a bill that will ensure the end of stalking and harassment during labor disputes. This law came about after Philadelphia Ironworkers union members intimidated people and vandalized property. A sponsor of the bill says that this will not affect peaceful labor disputes. However, Democrats are concerned that this law could affect freedom of speech rights among union members.
