For the third time in as many months, Hawke's Bay District Health Board's anaesthetic technicians have taken industrial action.
This time, however, it will be 7am tomorrow morning before they return back to work.
The strike is the result of a long running dispute about pay and conditions, and comes on the back of last week's failed negotiations between union; the Association of Professional, Executive, Clerical and Computer Staff (APEX) and the HBDHB.
They have been in talks since July, when the previous contracts expired.
APEX national secretary Dr Deborah Powell said the offer from the DHB represents a "step backwards".
"... it undermines Hawke's Bay DHB's current position as a leading public employer of Anaesthetic Technicians."
