The scheme aims to encourage people with low incomes to attend more training workshops and job interviews.
Courtney Buses, White Bus Services and Bear Buses have signed up to the scheme which is also supported by First, Arriva and Thames Travel.
Cllr Geoff Hill, cabinet member for highways and transport, said: "I applaud our local bus operators, and those who help service the larger national bus network, for helping those struggling to find their first job or indeed return to the workplace."
The Bus for Jobs national initiative, organised by the Greener Journeys sustainable travel campaign, is open to holders of a Jobcentre Plus travel discount card and will entitle the holder to free travel on participating buses.
