While you might be dreaming about the day you can clock off work forever — why are we instead seeing so many people leaving the green and re-opening the laptop?

It's all part of a trend being dubbed the 'great unretirement', in which 40% of the nearly half a million people who entered the labour force in the last three years were over the age of 55. Which has led to Australian workers now retiring at the oldest age since the early 1970s.

So, what's driving it? And who are the people getting back into work when they're meant to have their feet up?
