The Public Servants Union has vowed to fight for its slot at the Salaries and Remuneration Commission.
The newly-registered union declared that the country has two labour centres with Confederation of Public Servants Trade Union representing public servants and Cotu the private sector.
Yesterday, Pusetu asked all public servants union to secure representation under Pusetu.
"We shall secure all representation at all national and international organisations including the ILO," Pusetu deputy secretary general Charles Mukhwaya said adding that the union will reclaim its position in all matters related to labour.
The current workers' representative at the Salaries and Remuneration Commission which was established to guide public servants salary negotiations is a representative from Cotu.
The matter however has been contested in court and a ruling delivered against this particular representative.
Pusetu treasurer, Njeru Kanyamba said the commissioner at the salaries agency was illegally occupying office.
"We shall move to court for the contempt act against the member who continues to sit on the commission yet he does not represent public servants interests," Kanyamba said.
He has been restrained by the court, Pusetu said.
"Nobody should point an accusing finger to us because we have not done anything wrong," he told Cotu and advised it to direct its anger to the court which found Pusetu registration timely.
On Wednesday, Cotu executive board sanctioned its secretary general to thwart activities of Pusetu after it found out that the new union was out to interfere with it.
