The GWU is considering legal action against Transport Malta after the regulator reportedly started issuing fines against Arriva bus drivers who do not wear their tie.
The drivers were ordered not to wear their tie by the union on Tuesday. The union said at the time that it had issued its directive because of excessive heat. It also claimed discrimination, saying that other workers, including TM's own employees, were not required to wear their tie.
Transport Malta argues that the tie is part of the drivers' uniform.
Yesterday, many of the drivers were seen wearing their tie, without fastening it.
The GWU and Arriva are currently holding talks on a new collective agreement, with the union calling for better pay and conditions.
