I'm not sure if wage growth.... The world of service industry today is highly competitive. When you have Amazon, as an example, paying people $23 an hour as a starting salary to work in an Amazon warehouse just off the end of the runway at Pearson, and Air Canada is hiring people at $18 an hour, there's a problem going on in this process. Can regulation fix that? Probably not.
The marketplace is the way in which you have to recognize what the dynamics are of the hiring that you're doing and the wages you're paying. Unfortunately, aviation wages are now second fiddle to some of the other organizations hanging around airports.
