The lecturers said that unless Prof Kibwage is allowed to manage the institution, they will not honour the deal.
When he signed the return-to-work formula deal, Prof Kibwage assured striking lecturers that they would be paid their salary arrears for November from this month.
The leadership crisis at Egerton University deepened on Friday when more than 500 lecturers who had signed a return-to-work formula abandoned the deal.
The deal was signed by the acting Vice-Chancellor Prof Isaac Ongubo Kibwage and Universities Academic Staff Union (Uasu) national officials led by Chairperson Muga K'Olale and officials from the union’s Egerton Chapter.
