You have the right to stop industrial action if it is unlawful and affects goods or services being provided to you. You must be acting as a citizen, ie not representing a company.
The industrial action must either be likely to:
prevent or have prevented you from receiving any goods or services produced by a company
lower or have lowered the quality of those goods and services
This is called the ‘citizen’s right to prevent disruption’.
Apply to the courts for an injunction, which orders:
the trade union to stop organising the action
those taking action to stop
You can get legal advice if you want to apply for an injunction.
Further information on stopping industrial action: citizen's rights can be found on GOV.UK's website.
