Onyonka highlighted the low number of teacher recruitments in Kisii County, stating that only 133 teachers have been employed in the region.
He described the current employment system as operating like a casino, where success depends heavily on personal connections rather than qualifications.
According to Onyonka, candidates must demonstrate loyalty and "love" for the President to receive appointment letters. He alleged that without such favoritism, opportunities go to the President's friends, sidelining meritocracy entirely.
He further claimed that official TSC policies on fair and competitive hiring are no longer being followed, raising concerns about transparency and equity in public sector appointments.
The senator's comments, made in a panel discussion, have amplified ongoing debates about political interference in teacher recruitment processes.
Critics argue that such practices undermine the TSC's mandate as an independent body responsible for hiring, deploying, and managing teachers across Kenya.
Recent national recruitment drives, including announcements of thousands of new hires, have not translated into proportional benefits for regions like Kisii, fueling local discontent.
Onyonka's statements reflect broader frustrations among educators and aspirants awaiting permanent positions, especially in underserved counties.
Observers suggest that these allegations could prompt calls for investigations into TSC procedures and greater accountability in how employment letters are distributed.
As public education faces staffing shortages and quality challenges, the spotlight on favoritism risks eroding trust in government institutions.
The TSC has yet to issue an official response to the claims, but the issue highlights persistent tensions between political influence and professional standards in Kenya's education sector.
