"When Mr. Carey was informed there might be problems here, the first step he took was to say that if these people were involved in lawful picketing, we weren't going to cross the lines," said the spokesman, Matt Witt.

These restricted lawful picketing to the pickets' own place of work and removed the unions' legal immunities from civil actions, so making them liable for damages up to a certain limit where they were responsible for unlawful industrial action.
