The nurses union is considering expanding its industrial action if a deal with the state government is not reached soon.
Current action includes refusing to do paperwork and claiming all entitlements.
The union is unhappy about inexperienced nurses being used in management roles and the number of double shifts nurse are being asked to do.
On average it says there are two double shifts worked every day at the Royal Hobart Hospital and the Launceston General Hospital, and last week there were ten double shifts worked at the LGH alone.
Neroli Ellis from the Nurses and Midwives Federation has told 7:30 Tasmania overtime bans may be considered if there is no progress with talks.
“A 24 hour ban on double shifts across the state would bring our health system to a standstill,” she said.
The current pay agreement expires in December.
