Lilian Macer, the new Scottish Secretary of Unison said: "My priority and focus of the last two weeks has been engaging with those branches to make sure we get the highest turnout. Membership participation in the ballot process." 

“And our members are telling us that they are angry that the Scottish Government is not recognising and rewarding the contribution they make and they are angry enough to take action.”
