Despite the rubbish HR bods and "senior executives" regularly trot out to justify their roles, not EVERYONE has to be a leader. As long as you're happy or at least content, and have your health, and enough to pay the bills with a little bit left over, whose business is it anyway?
Said as someone who was ambitious in their mid-twenties to early forties, and did reasonably well, before realising what a load of absolute reinvented rubbish most of it is, getting ill, and dropping a few grades to a less stressful, much happier job. And it is a JOB for me now, not a career.
Even if there are days when I get exasperated that the bright bouncy 24 year olds with no ruddy life experience are bouncing into NHS Band 8as and above after a few months in the workplace, it's not that I want those roles. I'm just exasperated they weren't there when I had the energy and desire to still do them. I gather from friends in other professions that this pattern of life-inexperienced managers is being repeated again and again, not just in the NHS and nursing, but in many other sectors as well.
Of course the bright young things are much younger, way more obedient, and less cynical than us oldies as most of them haven't been through even one full cycle of (dis)organisational insanity yet....
