Police and witnesses said several hundred workers from Opex and Sinha Group took to the highways around 9:30 am and staged sit-ins there, disrupting traffic.
The workers said they did not receive their salaries for the last 4-5 months and the authorities concerned have shut down factories without any prior notice.
Besides, they claimed, they did not receive their Eid bonus during Eid-ul-Fitr either.
However, a 12-km long tailback has been created on the two major highways till filing of the report 2 pm on Thursday, causing immense sufferings to passengers.
Hafizur Rahman, officer-in-charge of Sonargaon Police Station, said, “Efforts are on to solve the problem and clear the highways.”
