Workers under the First Union umbrella will go on strike for 24 hours from 6am on Wednesday.
They are set to do the same again on Saturday, angered at what they say is an unwillingness from St John management to offer any sort of compromise deal.
Sarah Stone, First Union's national ambulance co-ordinator, speaks to Susie Ferguson.
