I think those at regionals and supplementals now should look really hard at long term QOL. Yes, regional and supplemental pay is not as good compared to the majors. However, what are your goals in life? How much does work schedule, vacation, and desk assignment matter?
Consider this. Most of the hiring done the past decade has been of dispatchers under the age of 50. Many under the age of 40. This means that significant portion of major seniority lists have 30-40 years before they consider retirement. When they get the desks, schedule, and vacation days they like and don't want to give up, which tend to be the more desirable in general, it will likely be a long wait for those that get hired over the next 10-20 years to get those desirable spots. It will also mean a constant stress over potentially being furloughed during each crisis or economic hiccup being in the bottom part of a long list with little to no retirements in sight.
I think the question that many have to ask is how long is working midnights, weekends and vacation in the winter going to be worth the higher major salary? In some parts of the country, a regional wage is not bad especially with overtime. If you attach yourself to a love interest with a well paying job, it might be better QOL wise to stay where you are.
If majors dont hire much if at all for the next decade, many now at the regionals will be in a different stage in life. As I have seen at a major already, the grass isnt always greener. The money is not always worth it. There is no shame in chasing after QOL instead of money or job titles.
