It ain't over yet. Beleaguered Qantas Airlines faces more turbulence ahead as the Transport Workers Union (TWU) pushes for successive work stoppages this and next week.

Engineers doing heavy maintenance work on Qantas aircraft at the Melbourne and Brisbane airports will strike whole day Friday, a spokesman from the union Australian Licensed Aircraft Engineers Association, said Wednesday. Meanwhile, the airlines' baggage handlers' group said their second industrial protest against the Australian airliner could happen as early as next week.

The workers are pressing Qantas to insert job security clauses in new employment agreements after the airlines announced plans to create Asia-based budget carriers to stem business losses. The approach would involve closing money-losing routes and laying off 1,000 jobs.

On Tuesday, about 4000 Qantas baggage handlers and ground staff held four-hour work stoppages at major airports across Australia.

Qantas was forced to cancel 28 domestic flights and make 53 scheduled changes. More than 6,000 passengers were affected.

Qantas shares nearly moved on Wednesday, posting only a 0.3% hike, while rival Virgin Australia Ltd. increased 3.3%.

With Qantas' workers getting restless each passing day, more people will surely fly with its main rival to avoid travel interruption
