In the face of growing competition, it was announced that Central Scottish would be merged with Kelvin Scottish in an attempt to make the larger company more attractive to potential buyers. However, the planned merger was deeply unpopular with Central's staff, as flexible rostering agreements, fully in place with Kelvin, had not yet been implemented at Central. This resulted in a disastrous strike in early 1989, and the company's network was paralysed for weeks on end. While Central's buses remained in their depots, Strathclyde Buses and a number of independent operators stepped in and took over much of the company's route network. By summer 1989, the dispute had ended, and in a vain attempt to win back customers, Central embarked on a major rebranding exercise. The Central Scottish trading name and the deep red and cream livery the vehicles wore gave way to a number of new local identities. Vehicles in Airdrie received a dark blue and grey colour scheme branded as Monklands Bus, East Kilbride vehicles gained a dark green and cream livery with EK Chieftain fleetnames, leaving vehicles in the remaining depots gaining a more vibrant red and cream livery, branded as Lanarkshire Bus. The Central Scottish identity was buried with the strike action, and the company was renamed Kelvin Central Buses in preparation for the merger. However, a significant retrenchment of the company's operations followed.
