Workers of TNZ Apparels Ltd in Gazipur blocked Dhaka-Mymensingh highway in Maleker Bari area of Gazipur city demanding their unpaid dues.
The protest began around 9:30AM on Saturday, halting vehicular movement on the highway.
The blockade caused a heavy traffic congestion several kilometers long in both the Mymensingh and Tangail directions, as well as towards Dhaka.
Bason Police Station OC Rahedul Islam said that the workers of different garment factories including TNZ Apparels Ltd staged demonstrations in the last several days for the payment of their wages for three months.
As their salaries remained unpaid, workers of TNZ Apparels again blocked the highway in the morning, causing immense suffering to the commuters.
However, police are trying to disperse them from the highway.
