The police union is worried about being included in a review of the state service.
Premier Will Hodgman said it had been nearly 20 years since the State Service Act was developed in the late 1990s and a review would ensure the future needs of Tasmanians would be met.
However, Police Association of Tasmania president Colin Riley said the union had been "informally advised" police would be part of the review.
"This is peculiar as police officers' employment is regulated by the Police Service Act 2003 which is completely separate to other categories of state service employment and has historically been treated accordingly," Mr Riley said.
"In the absence of clear detail as to how this review will progress, the PAT is apprehensive as to police being rolled into a state sector process.
"It will be seeking additional information from government and assurances that there will not be any negative implications for our members."
Mr Riley said police work was difficult and support from government was vital to providing "a high quality service to the community".
Community and Public Sector Union secretary Tom Lynch supported the Premier's review but was worried there was only one union voice on the steering committee overseeing the review.
"We hope the government is committed to a full and open review,"Mr Lynch said.
"We are concerned the government has proposed only one worker voice on a 10 person steering committee and will seek to have this changed in our feedback on the terms of reference."
The review, to be conducted by Dr Ian Watt AC, a former public servant, has nine draft terms of reference including examining the feasibility, effectiveness and efficiency of further decentralisation of government services.
Mr Lynch said in his view moving Mineral Resources Tasmania to Burnie had not been successful.
"There has been a very high turnover of staff and the four years has been characterised by waste and mismanagement," he said.
"People got sick of travelling and left and there has been trouble filling vacancies."
The review of the state service does not include wages policy or conditions.
Feedback on the draft terms of reference close on November 29 and the review is expected to be finished by the end of 2020.
