Ambulance workers say the call to strike boils down to ensuring their voices are heard. 

2,500 members from First Union and the Ambulance Association have voted on industrial action. 

Labour will be withdrawn for four hours across two days —August 20 and 24— amid calls for the Government to fulfil an election promise to renegotiate funding. 

First Union spokesperson Faye McCann told Ryan Bridge 95% of its members voted to strike. 

She says it's unfortunate and not the ideal situation. 

The Government says it will continue with the current contract for now.
