Workers at the National Gallery in London have voted to support a strike against cuts to security at the gallery in an indicative ballot.
Almost 180 gallery assistants in the PCS union voted by four to one to support action.
This is in response to plans for one assistant to keep watch over two gallery rooms rather than one.
Any action could potentially disrupt the popular, and lucrative, Leonardo
Da Vinci exhibition at the gallery.
A formal ballot will now need to take place to call members out.
