Read this post and thought in the interests of fairness a few things should be highlighted.1) The title is misleading, both Tower and Approach are paid the same wages, although currently the two are on differing shift patterns.2) The timing of the post is interesting. Historically shifts have always changed in Tower at this time of year due to the annual religious holiday and the large number of staff that request time off due to this. The Tower controllers have actually been working the same hours for the last month and a half. Interestingly though no complaint was made from approach during August when the Tower guys ended up working morning night shifts on the same day. Now that this has changed apparently its a big deal.3) In terms of rostering approach end up with a better pattern overall. They at least have some form of watch system and know that their shift pattern remains fairly constant. Tower do not have this luxury and it is not uncommon for them to be called in on their days off to cover shifts. When a shift pattern only allows for 1 sleep day and 1 day off at the end of a cycle you can appreciate that the situation isn't ideal. Therefore whilst on paper they work less the reality is that some **** cycles can turn into 8+ days on shift without a day off.4) It is unfair to suggest that the approach controllers are busier. The fact remains that it is a very busy international airport with complex traffic patterns and a wide variety of users. Both tower and approach have their intricacies and work hard at what they do. The current situation probably isn't ideal for either side of operations but steps are being taken to increase staff numbers and when that happens hopefully everyone will be happy. Until then it really doesn't help to bicker and it is better that people remember that whether you are approach or tower you are, at the end of a day, a team who should support each other.
