I think I grasp what the gist, the whole system is assuming that employers are doing things as they are meant to be done via the legislation but a lot of companies make it nigh impossible to book AL in a way that is viable - "Yes you can have this week off you've requested in ten months time, apart from the Tuesday and Friday" - Bang goes the weeks vacation wherever you wanted to go at the affordable price you found... It's flattering to a point if your boss / HR don't consider you being away for an actually useable amount of time but also part of that wave of chipping away at people's rights, kick up a fuss referring to the rules and regs and you are earmarked as troublesome.
On the last point, shut up and get back on the hamster wheel
