Newfoundland and Labrador doctors will put the government's latest contract offer to a vote next month, according to a letter from their association.

The Oct. 14 letter said the Newfoundland and Labrador Medical Association is putting the April 20 offer to a vote because it is frustrated with the government repeatedly rejecting its counter-proposals.

"Members want a satisfactory conclusion to what has been a frustrating and protracted negotiations process. It is also clear after repeated, rejected counter-proposals that government is not willing to budge from its original offer of April 20, 2010," states the letter.

The two sides have had sometimes acrimonious negotiations for more than 18 months. The doctors' last four-year agreement expired more than a year ago.

Last March, both provincial Health Minister Jerome Kennedy and Premier Danny Williams lashed out at doctors, describing them as squabbling children.

The letter signed by assocation president Dr. Pat O'Shea said ballots will be mailed to the province's more than 1,000 doctors in mid-November.

The association expects to have results by early December.
