its a PAP lite logic. but a very different one. for PAP, they keep increasing the retirement age from last time 55 now i think 64 le. what this means is alot of companies, will drop older workers their position, which comes with a drop in salary and benefits, to prepare them for re-employment into easier jobs as they hit the retirement age. with removal of retirement age, older workers gets their choice to work at full benefits until they dont feel like working anymore.
that said, i dont fully agree as it opens up a can of worms of possible JLB old folks refusing to give up their position for younger and more promising workers to bring the company forward. they will be drawing full salary and wasting company resources too.
