I wouldn't worry about it at all. There are a great deal of current pilots reaching their retirement point, and this will continue for the next five years or so to the number of two hundred or more pilots per year (so-called Hamble bulge). The company does not wish to repeat this to such an extent and therefore is at the moment recruiting a constant number continuously while also recruiting DEPs as well. If you take a look at aircraft orders, there is no let down in the number of bums needed on seats, and unless the world economy goes down the pan in the next few years, you'll be fine.
