With automation increasing, many workers are becoming obsolete – and UK insurer Aviva is willing to admit it. The company is retraining all employees who feel a bot could do their job, aiming to equip them with new skills in a bid to keep them dedicated and happy before automation sets in.

The PR industry favours the young, but often requires employees to work past retirement age. Knowing that it may be hard to find your place if you’re not part of Gen Y, Wunderlich Kaplan Communications is offering a new internship to women over 40. But is age really just a number?

Reaching retirement age used to mean kicking back and cruising through later life. But rather than heading to the golf course, a growing number are staying in work. The US now has its highest number of elderly workers since the '60s as Seniors continue to clock in.

"We just don’t do old age like my mum and dad did," says 50-something director Sue Bourne. "This generation keeps working, they’re still active. It’s the beginning of a revolution in ageing." And from cosmetics to housing, it’s creating a new and profitable opportunity for entrepreneurs everywhere.
