Miami, September 23, 2010: Adecco Group, the worldwide leader in Human Resource
services, is holding its Investor Days 2010 in Miami today and is providing an
update on current trading conditions. Adecco continues to see good demand in the
majority of its markets and sees no signs of a slowdown.  Revenues in July and
August continued to develop inline with June, increasing by approximately 16%
organically and adjusted for business days.

In the first two months of the third quarter of 2010, Adecco's revenues
continued to grow double-digit, up approximately 16% organically and when
excluding the business day impact. Demand remained robust across most markets
with no signs of a slowdown and management continues to be confident in healthy
demand progression near term.

While the company continues to exploit the much improved conditions, focus on
diligent cost management and financial discipline is strongly maintained. At its
Investor Days today, the management remains firmly committed to its mid-term
EBITA margin target of above 5.5%. The results achieved in the recent quarters
underline that the company is well on track.
