Practice 4　　In the first year or so of Web business, most of the action has revolved around efforts to tap the consumer market. More recently, as the Web proved to be more than a fashion, companies have started to buy and sell products and services with one another. Such business-to-business sales make sense because businesspeople typically know what product they’re looking for.　　Nonetheless, many companies still hesitate to use the Web because of doubts about its reliability. “Businesses need to feel they can trust the pathway between them and the supplier,” says senior analyst Blane Erwin of Forrester Research.

This will be led by younger, less-experienced employees and the hard - headed young graduates. ‘Headhunters’ confirm that older staff are still cautious, having seen so many good companies ‘go to the wall’, and are reluctant to jeopardize their redundancy entitlements. Past experience, however, suggests that, once triggered, the expansion in recruitment will be very rapid.　　The problem which faces many organizations is one of strategic planning; of not knowing who will leave and who will stay. Often it is the best personnel who move on whilst the worst cling to the little security they have. This is clearly a problem for companies, who need a stable core on which to build strategies for future growth.　　Whilst this expansion in the recruitment market is likely to happen soon in Britain, most employers are simply not prepared.

Without this ability to recruit competitively for strategic planning, and given the speed at which these changes are likely to occur, a real crisis seems imminent.　　SUMMARY:　　Taking all of these various factors into consideration, when the economy picks up and people 　1　there will be a very rapid expansion in recruitment.
