The firefighting crisis rocking the Andrews government has been thrown into further turmoil with the CFA board declaring that it cannot sign the proposed pay and work deal with the union.

The decision, following a board meeting on Monday morning, will place further pressure on Premier Daniel Andrews to compromise on the pay deal with the United Firefighters Union which he has been backing.

The CFA board meeting happened as Mr Andrews met with his embattled Emergency Services Minister, Jane Garrett, who is understood to be considering quitting over the whole saga.
