Welsh ambulance workers have voted in principle for industrial action.
The GMB union, which represents around 1000 people, asked its members if they would be willing to take action if a formal vote was called.
For those in favour of taking industrial action short of a strike the result was 63%.
For those favouring a strike option the result was 41%.
Members also supported a vote of no confidence in the Ambulance Service management.
In order for formal industrial action to take place, the union would need to re-ballot the members.
Any form of action is likely to be around 'work to rule' which could have a significant impact on an already struggling service.
This will be the news the ambulance service dreaded. The Unite union has also balloted its members but the results have yet to be announced.
