The reality is that you are competing against people who have been increasing their skill at relevant tasks and you have not. It's no more complicated than that. Fairness has nothing to do with it.
That makes no sense, for so many reasons. Here's one: 10 years of experience with a 6 month break is worse than 5 years of experience and a 2 month break? Here's another: skill increase is not linear. Here's another: People are different.
Unfortunately, HR departments do not have the time or resources to take into account differences in individuals. When looking at two resumes, they have to evaluate them based on certain criteria, and they have to assume that all other things are equal. (They rarely are, but life is unfair like that.)
