Especially for Ah Wai
The Tower Controllers leave their work for home two hours earlier than their official sign off time, this early-go is not registered. These people now claim the Management for TOIL. Two hours each day 20 days a month then each month each tower controller shall be deducted 40 hours from their base figure. As time goes by these TOIL argument is not a problem anymore. 18,000 hours??!! NO PROBLEM!
If tower controllers persist the pursuit, they should file a lawsuit to CAD, Let the judge to write off the TOIL and the early-go !
