Transport Workers Union (TAWU) demonstrated against the implementation of the Bus Rapid Transit (BRT) system.
According to the union, the government has been holding secret meetings and they have not been involved in the process.
On Friday, the workers demonstrated in Nairobi in a bid to hand their petition to Transport Cabinet Secretary James Macharia.
Involvement of all sectors
TAWU General Secretary Dan Mihadi said: "They have Matatu Owners Association on board but not us, the people who work on a day to day basis."
He added: "We are the ones with the technical knowledge of the day to day running of the Industry, we should be included.”
Mihadi argued that if the implementation was not well coordinated to include public transport workers it would not be devoid of controversy.
BRT take over
“The BRT comes with job opportunities for all of you, we will work with your union leaders to see Matatu workers are represented," he said.
Thika Superhighway has been demarcated red with words "BRT ONLY" a sign for drivers to stay away as the country prepares to usher in the Bus Rapid Transport system.
The lane will be dedicated to facilitating easy movement of all high capacity PSV buses carrying over 80 passengers.
This is with accordance with the government's push to decongesting the city and facilitating easier movement in the country's economic hub.
