The Council of Academic Staff Unions of Osun State -owned tertiary institutions has suspended its strike following an agreement with the state government on its demands.
This followed a peace meeting between the unions and the state government on Tuesday in Osogbo.
The Chief of Staff to the Governor, Gboyega Oyetola, who represented the state government signed an agreement with the union leaders to end the strike.
The affected institutions are the Osun State Polytechnic, Iree; College of Technology, Esa-Oke; as well as the Colleges of Education in Ila-Orangun and Ilesa.
Francis Ademiluyi and Olusoji Fadipe also signed the agreement on behalf of the teaching and non-teaching staff of the unions respectively.
The unions agreed to suspend the strike having agreed on the modalities to pay the 2009 consolidated salary of tertiary institutions. They also agreed on the 2009 Consolidated Polytechnics and Colleges of Education Staff Structure (CONPCASS).
The meeting agreed that the issue of the 65 years retirement age had become a legal matter which would be adequately taken care of by the state House of Assembly.
Mr. Oyetola had earlier read the agreement which included the payment of 90 per cent of the 2009 consolidated salary structure.
Addressing newsmen after the meeting, the union leaders directed their members to resume work immediately
In attendance at the meeting were some members of the State Executive Council, including Sunday Akere, the Commissioner for Information and Strategy.
The strike began in 2012 over the demand for implementation of the Consolidated Tertiary Institution Salary Structure and approval of 65-year retirement age for lecturers.
