Navigating meals can be troublesome with children, but a kebab, bought on the street or in restaurants, was unfailingly popular.

The looming demographic cliff will see vast numbers of skilled workers dispatched from the labour force. The workforce is ageing across the rich world. Within the EU the number of workers aged between 50 and 64 will increase by 25% over the next two decades, while those aged 2029 will decrease by 20%. In Japan almost 20% of the population is already over 65, the highest share in the world. And in the United States the number of workers aged 5564 will have increased by more than half in this decade, at the same time as the 35 to 44yearolds decline by 10%. Given that most societies are geared to retirement at around 65, panies have a looming problem of knowledge management, of making sure that the boomers do not leave before they have handed over their expertise along with the office keys and their address. A survey of humanresources directors by IBM last year concluded: When the babyboomer generation retires, many panies will find out too late that a career39。 the rest of the developed world tomorrow? If you look hard enough, you can find panies that have begun to adapt the workplace to older workers. The AARP, an American association for the over50s, produces an annual list of the best employers of its members. Healthcare firms invariably e near the top because they are one of the industries most in need of skilled labour. Other sectors similarly affected, says the Conference Board, include oil, gas, energy and government. Near the top of the AARP39。 Company, a nononsense industrialequipment manufacturer based in Illinois。s 46,000 employees are over 50 and a number of them are in their 70s.

The pany spends a lot of time on the ergonomics of its factories, making jobs there less tiring, which enables older workers to stay at them for longer. Likewise, for more than a decade, Toyota, arguably the world39。 Young, a professionalservices firm, has about 30,000 registered alumni, and about 25% of its experienced new recruits are former employees who return after an absence. But such examples are unusual. A survey in America last month by Ernst amp。 and even fewer are looking to them to fill another gap that has already appeared. Many firms in Europe and America plain that they struggle to find qualified directors for their boards this when the pool of retired talent from those very same firms is growing by leaps and bounds. Why are firms not working harder to keep old employees? Part of the reason is that the crunch has been beyond the horizon of most managers. Nor is hanging on to older workers the only way to cope with a falling supply of labour. The participation of developing countries in the world economy has increased the overall supply whatever the local effect of demographics in the rich countries. A vast amount of work is being sent offshore to such places as China and India and more will go in future. Some countries, such as Australia, are relaxing their immigration policies to allow much needed skills to e in from abroad. Others will avoid theneed for workers by spending money on machinery and automation. 16.

B. a decrease in the number of 35 to 44 yearolds. C. a continuous increase in the number of 50to 64yearolds. D. its impact on the developed world whose workforce is ageing. 17.
