The Kenya Union of post-Primary Teachers education has accused the Kenya National Union of Teachers of behaving like a political party.

Kuppet national deputy secretary Moses Nthurima and Isiolo branch secretary Mwiti Gichunge told members in Isiolo during an annual general meeting that Knut should sober up.

"Knut is our sister union and they must stop stage managing issues claiming that Kuppet members are defecting to them," said the deputy National secretary.

He said Kuppet will continue to negotiate salary increments for all teachers after Knut boycotted the meetings. The two unions have lately traded accusations in their quest to gain more members.
