For whom the bridge tolls

I understand that unions are keen to protect the interests of their members but such action is only legitimate when it's compatible with a free market.

The proposed removal of Scottish bridge tolls has produced this comment:

The decision to scrap tolls on the Forth and Tay bridges has been attacked by the Transport and General Workers Union due to concerns over job losses.

I support the idea of road pricing. Does the T&GWU (how 1970's that sounds) want road privatisation? Perhaps they should.
