Tasmania is on the brink of minority government but Premier Will Hodgman has brushed aside concern, insisting the Liberals are getting on with the job.
Rogue Speaker Sue Hickey is considering quitting the Liberals after being overlooked in a weekend cabinet reshuffle.
Ms Hickey, who voted with Labor and the Greens to become Speaker last year, is disappointed about her lack of influence in the party and said she will decide by the end of the week whether to become an independent.
"I'm seriously considering it," she told ABC radio on Monday.
"Forces within the party ... prevent me from ever being considered.
"If that's the case then maybe I just get on with being the best Speaker I can be ... probably as an independent."
Ms Hickey said she was embarrassed by the government's handling of health, affordable housing and public sector pay rise negotiations and called Mr Hodgman's leadership "weak".
"I don't think Will is strong enough to handle the team," she said, adding she found out about the reshuffle moments before it was announced.
"I get a phone call ten minutes before he tells the world. Do you think that's treating me like a team member?"
"I have been publicly excluded from the Liberal Party."
Ms Hickey has guaranteed the government her continued vote of confidence and supply if she decides to quit the party.
Mr Hodgman says that means it is business as normal.
"I'm pleased that she has said very clearly again that she will continue to provide support for the government," he said.
"My leadership is dependent on the ongoing support of all my colleagues. I have their support, their confidence.
"We continue to govern in majority and we are determined to do what we were elected to do."
Since being elected, Ms Hickey has crossed the Lower House floor to pass several pieces of legislation, including making gender optional on birth certificates.
Including Ms Hickey, the Liberals hold 13 seats in the House of Assembly to Labor's 10 and the Greens' two.
Sunday's cabinet reshuffle saw under-fire Health Minister Michael Ferguson dumped from the portfolio and moved to infrastructure and transport.
