“The Ministry of Labour cannot purport to run a trade union. The union must be allowed to engage in its activities within its constitution,” Mr Sossion said.
He said the first port of call for any complaint by a union official is the leadership of the organisation.
“You cannot petition the government to defend you,” he added.
Mr Sossion said the issue will be presented to the 44-member National Executive Council (NEC) for directions.
Trouble at the union started on November 7, when Mr Nzili wrote to Mr Sossion, asking him to vacate office following his nomination as Orange party MP in August.
In Mombasa, the NEC has started its four-day retreat to set the agenda for the 60th annual delegates conference that will run from December 13 to 15.
In the coastal town, Mr Sossion and Mr Nzili put a brave face, insisting that there were no wrangles in the union.
“There is no fighting. There are no wrangles. It’s just a meeting,” Mr Sossion told journalists.
“We have nice things for teachers. I will talk about the issue of resigning at the appropriate time. I will be at the Coast for four days,” the trade unionist said, as he walked hand-in-hand with Mr Nzili.
However, Knut’s Coast branch executive secretary Tom Kitu Gwengwele said the union would take legal action against the MP if he refuses to quit.
