At least 496 members of the Airport Police Department (APD) were subjected to urine drug testing on Wednesday in compliance with its drug-free workplace policy. Manila International Airport Authority (MIAA) General Manager Ed Monreal said the APD was the first group of the 3,000 organic and non-organic employees of the MIAA who underwent random testing to ensure the airports are run by non-drug users. The testing was performed by an outside third party accredited by the Department of Health and for which the MIAA paid a total of P133,920. The result will be known within the week, Morneal said. Last June 27, at least 3,000 drivers from the Airport Shuttle Service Inc. (ASSI), a private transport concessionaire accredited by the MIAA, underwent annual drug testing. ASSI chairman Romeo Sayaman said drivers found drug-positive have been subjected to disciplinary action or immediate termination with no appeal.
