Do I have to go on strike when UNISON takes industrial action?

Industrial action is always the last resort for the union, and may happen when negotiations have broken down and where any agreed disputes procedure has been exhausted.
 
UNISON’s main objective is to get the best possible deal for members. The union will inform members of the reasons why any industrial action is being considered and will ballot all members (including both BAOT and UNISON members) it intends to call upon to take action, so that all members have the opportunity to vote on whether or not you wish to take industrial action. 
 
If following a ballot, the decision is made to take industrial action UNISON will encourage all members to participate - as it’s the strength of turnout which will make the action successful. Trade unions cannot discipline members who refuse to participate in industrial action. However, the union does expect members to abide by the decision of the majority expressed in a legal and democratic ballot of its members.
