Staff at a Forth Valley bus manufacturing company are to begin industrial action from today.
Workers at Alexander Dennis, in Larbert and Camelon, will strike until Friday.
Unite confirmed it's in a dispute over pay.
A second of strike action will begin in October.
Pat Egan, Unite industrial officer said; “Unite has engaged ADL in direct talks for months now to find a resolution to this pay dispute. However, despite having a very healthy order book, the company refuse to make our members an offer which their world class work deserves. Our members have been forced by the company to take this strike action and they will continue to take action until the company sees sense.”
