I'm curious. So what do you belive I should be paid then? According to the BLS the average person dealing with bags in all industries make about $12.00 per hour. That's the true "Market" for that job. Unions are not supposed to be dictated by the market though for your information. They're supposed to try to raise that bar.
If the market were a living breathing entity and you went in front of it and asked what it wanted to pay you, I can tell you what it would come back with. Minimum wage. The lowest possible number it can get or force you to take. That's reality. It doesn't care about what you want or what you feel your needs are.
So you just like that market you quote believe you should be paid more than me, OH, the agents, FAs, support ataff, (Maybe the Pilots, management, The CEO, Tom Brady) McDonald's, Walmart.
Just remember that not everyone might think you're worth as much as you think you are. I bet the passengers who want the cheapest seat they possibly can get would also say, YOU'RE OVERPAID.
