One of the things I really resent about society/work/the man (call it what you will!) is the way that you're either in or you're out. There doesn't seem to be much of a middle ground tolerated. I'm a senior teacher and am not really well enough to work properly but neither am I poorly enough to retire medically yet. It'd be nice to have a choice in the matter but seemingly as long you can stand, it's quite hard to get medically retired in the UK during these times of 'austerity' (thanks bankers. You really screwed the world up nicely).
I get paid a good salary but am aware that I'm not as productive as I was and feel lots of pressure at work to either do as well as I used to or take a cut in salary or move to a lesser role. Whilst this is illegal, I do understand my bosses predicament: he has a 'half' manager who ought to be moved onto retirement but such is the economic situation, nobody is allowed this anymore unless you're at deaths door.
Funny old world innit?!
