PRIME MINISTER Kamla Persad-Bissessar has described the negotiations between Petrotrin and the Oilfields Workers' Trade Union (OWTU) a success.

"I think it was a win-win situation for the country, for the workers and indeed for the national good," Persad-Bissessar said on Sunday night.

She was speaking to reporters at the Patiram Trace Shiv Mandir in Penal while attending Shiv Raatri celebrations on Sunday.

"It is clear there never was a five per cent wage bar and I had repeatedly said that throughout, since the impasse started. I kept saying go back to the negotiation table, negotiate with your employers. ... Each enterprise would have a different kind of set up and what kind of income they can afford. Indeed, for the first year in many years, last year Petrotrin did make a profit ... so 2011 was a better year of Petrotrin," she said.

It was last week Friday Petrotrin and OWTU settled on a nine per cent wage deal, averting the threat of strike action by workers.

Persad-Bissessar credited Labour Minister Errol McLeod who she said "laboured long hours, many hours in those negotiations for bringing them finally to a close".

Speaking on the filing of a no confidence motion in her by Opposition Leader Keith Rowley last week, Persad-Bissessar said it was "frivolous, vexatious and without merit".

"I am not fazed by it. I believe there's a lot of support for the Government in the country, and most certainly I think it really shows his incompetence that he would want to file such a motion on such frivolous grounds, and which surely will be defeated in the Parliament. We are not afraid of it. We will be able to give us an opportunity to speak to our achievements as a Government throughout the debate in Parliament," Persad-Bissessar said.

The Prime Minister opted to visit temples in her constituency on Carnival Sunday for Shiva Raatri, a ceremony she has attended for over 20 years.
