Public university lecturers have threatened to go on strike at the end of October if the government fails to implement their CBA.
In a letter to the university governing council, they accused it of violating their rights by failing to give them their dues.
“All our members in all public universities and their constituent colleges shall withdraw their labour and shall not resume duty until the 2013-2017 CBA is implemented,” UASU secretary general Constatine Wasonga said on Tuesday.
Lecturers are yet to receive the increased pay as agreed on in March.
They had gone on a 54-day strike, which paralysed learning at institutions countrywide.
According to the registered CBA and return-to-work formula, the government and university councils said they would implement it by June 30.
At least 33 public universities and their constituent colleges across the country, with more than 500,000 students, will be affected.
The government awarded UASU Sh6 billion under the agreement to cater for salary adjustments for its members.
The amount was part of the cumulative Sh10 billion the government awarded three university unions that were pushing for pay rises for members.
They are UASU, Kenya University Staff Union and the Kenya Union of Domestic, Hotels, Educational Institutions, Hospitals and Allied Workers (KUDHEIHA).
