TAIPEI - More trouble is brewing for China Airlines (CAL), as Taiwan's biggest airline is bracing itself for a second possible strike in just one week.

This time round, the China Airlines Employees Union, comprising maintenance crew, pilots and ground staff, urged its members to "go on leave" this Friday (Jul 1) in protest against the airline's failure to meet their demands for better pay and work conditions.

The union announced that its members will go on mass leave after negotiation talks with the airline's management, including its chairman Ho Nuan-hsuan, broke down on Monday (June 27).

Union members are demanding that CAL's management give them similar benefits that the airline's cabin crew managed to get after they went on strike last Friday over changes in work conditions.

The first-ever strike by cabin crew in the island's history ended after CAL met seven demands, including an increase in their overseas allowance.

The strike crippled operations, grounded flights and left over 30,000 passengers stranded in Taipei.
