Tasmanian Liberals want public sector workers to keep their opinions to themselves in the run-up to the state election.

The chief-of-staff for Leader of the Opposition Will Hodgman has sent a number of letters to the Department Secretary for the Premier of Tasmania.

Liberal leader Mr Hodgman says a number of recent comments could be construed as political plugs, during a time when public sector non-partisanship is most important.

Mr Hodgman specifically complained about comments from Tasmanian Deputy Police Commissioner, Scott Tilyard.

Mr Tilyard said “further reductions of state servants would be difficult for us to absorb,” about a week before the government entered caretaker mode.

In another complaint about police comments, Assistant Police Commissioner Phil Wilkinson was accused of operating “outside of the standards expected” when he said that ABS crime figures showed Tasmania was a safe place to live.

A health department spokesperson has been similarly criticised for defending hospital waiting list data.

Other government agencies have been asked to stop tweeting in a forum about Tasmanian politics.

The Premier’s department has reportedly responded, saying caretaker conventions do not prohibit agency staff making statements of fact.

Liberal spokesperson Matthew Groom said it was about avoiding awkwardness.

“It's actually not about us, it's more about the public service... an election is an awkward period for the public service,” he said.

Reports say the complaints have not been upheld.
