ODM Secretary-General Edwin Sifuna has KNUT boss Wilson Sossion that Education CS Prof George Magoha's language during the engagement with the union was bad.
Magoha hit out at Sossion and other rebellious education officials over their opposition for the new curriculum.
The CS in a fit of rage termed the opposition by Sossion and ilk as "useless gimmicks aimed at intimidating him.
"Who the hell do you think they are?" posed Magoha adding that "this kind of politics should stop. I mean this is stupid."
His utterances were castigated by Sossion who said that it was unbecoming for a leader of his calibre to issue such statements.
Sifuna added that such language paints a bad image for a civil servant like Magoha.
"I am with SG Sossion on this one. Some of the language I heard Prof. Magoha employ yesterday is simply unacceptable for a public servant," Sifuna opined.
Magoha has been on an offensive with KNUT for asking its members to boycott the Competency-based Curriculum training and its implementation.
