First Aberdeen drivers accepted a deal in their terms-and-conditions dispute with the company, after drivers had previously voted for an ‘all-out strike’.
Unite's Regional Officer Willie Wallace says: "The union members have decided by a 3:2 majority to accept the latest deal offered by First Bus.”
First Aberdeen MD Andrew Jarvis said the business now has a "stable platform" for the long term.
In a statement, Mr Jarvis said: "We are delighted with the news that Unite the Union members have today voted in favour of accepting the new terms and conditions package, negotiated and recommended by their representatives earlier this week.
"This has been a challenging process for everyone involved, but we now must look to quickly mend relationships and get back to providing the best possible bus service for the city of Aberdeen.
"I would like to apologise to our customers for the disruption that they have endured over recent weeks but they can now be assured that First Aberdeen services will resume back to normal with immediate effect."
He added: "The new proposal includes a two-year pay deal that has been negotiated and agreed by both sides which will provide a stable platform for the business in the long term."
