Stung by a string of mishaps at Taiwan's main international airport, authorities there hope to bring back former airport workers to help give the facility a new lease on life, the Civil Aeronautics Administration (CAA) said Saturday. CAA officials acknowledged, however, that it will not be an easy task to persuade them to return to work at Taiwan Taoyuan International Airport because many took preferential early retirement packages to leave their jobs. The Ministry of Transportation and Communications (MOTC) ordered the CAA to hire back some of the best-performing retirees -- many of whom are still under 55 years of age and have good engineering and management savvy -- to help the airport cope with its current woes as it moves toward privatization, according to CAA officials. The Taiwan's largest airport is slated to become a private airport company in November, and many airport workers have applied for early retirement out of concern of facing bleak prospects and a loss of benefits under the new regime. To find the root cause of the many problems at the airport, including leaky restrooms, poor facilities, expensive food and staff misconduct, the MOTC has been holding meetings almost every day with officials from supervisory agencies. Meanwhile, airport authorities are planning to recruit some 50 new staffers, mostly engineers, in September. A Taoyuan Airport Improvement Task Force, set up in July by the MOTC, has described the three-decades old airport as being 'very ill' and vowed to raise its current world ranking from 27th to the top 10 in three years. According to the results of a survey conducted by the panel between July 23-27 at Taoyuan Airport's two terminals, passengers are mostly dissatisfied with 16 of the most important services at the airport, such as the high cost of food, the airport's surrounding landscape, defective luggage trolleys and unclear direction signs in the transit area.
