A statement said Grundy, who PRWeek was unable to reach for comment, ‘will leave the organisation in November. He will pursue other interests'.
Grundy played a central role in the launch of Adecco's visual identity earlier this year.
He joined Adecco in Hong Kong and took up subsequent PR roles in Singapore and New York. He was promoted to his current role just over 12 months ago (PRWeek, 17 Sep 2005).
The Swiss company has a network of 33,000 employees and 6,600 offices spread over 70 countries.
