I too am interested in this. Anyone who knows anything about aviation and ATC in particular, knows that the good ole days are gone. However, methinks that sooner or later, the system simply has to give in.
I've spent the better part of the last 10 years following trends in ATC, and one thing has certainly become more than obvious over the past few of those same years - just about every place around the big blue world of ours has fudged it up with prioritizing hiring qualified personnel. Essentially all of them are now in the "can't hire much at the moment, cause we don't have enough people to train AND work the scopes at the same time". Where will that lead us sooner or later? If we look at the state of the world and many an industry in those same past 10 years as any indication, it may all just crash and we'll do away with 99% of aviation OR if a desire to keep flying stays, the ANSP's will have little choice but to offer what needs to be offered. Who will train the new generations? Who knows.
As far as IAA goes, they've had their SCP for some time now. I myself applied in late 2014 and was invited to the testing in the spring of 2016. Naturally enough, I declined to take part, as they hadn't changed their stance on just about any aspect of providing a meaningful offer worthy of an ATCOs training and career.
I used to have a strong yearning not for aviation, but for this line of work specifically. I passed on the idea of professional flying long before even thinking about it, after I realized just what junky environment the pilot profession had turned into. Thanks to just about everything that has gone down in the recent years in the field of ATC, even after giving it just about every possible chance, benefit of the doubt and every last Joule of energy, the same has recently occurred with any former desire of mine to "work" in this area, even if given an opportunity(which is of course a whole different story in itself).
Working conditions (and pay) in ATC are going downhill. This can only lead to industrial action and strikes. Some governments and ANSPs have been playing dirty tricks for years and it's time to respond accordingly.
