According to reports, five people from creative and account servicing have been axed already, with more jobs to go before Christmas.
Other staff have already resigned, including Bob Nelson, head of broadcast production, and John Russo, co-executive creative director.
Publicis Groupe CEO Maurice Levy took the decision to close D'Arcy following the acquisition $3bn (£2.1bn) of Bcom3 in September. After the acquisition, Publicis was left with five international advertising networks: Saatchi & Saatchi, Publicis Worldwide, Leo Burnett, Fallon Worldwide and D'Arcy.
D'Arcy's accounts have already been fielded out to fellow Publicis Groupe agencies. Procter & Gamble, one of the world's biggest advertisers, has restructured its advertising roster, shifting work away from D'Arcy and also from Havas-owned Arnold Worldwide.
The Publicis Worldwide network picks up P&G brands including Bounty, Charmin and Tempo. Leo Burnett has been awarded Always/Whisper, the deodorant brand Mum and Fairy Laundry; while Saatchi & Saatchi's new brands include Folgers coffee and the dental care brands Crest and Fixodent.
Although D'Arcy has been around since 1904, and responsible for iconic advertising such as Coca-Cola's red and white Santa Claus image in 1934, in recent years it had become uncompetitive. The final nail in the coffin was the loss of the Mars and Pampers accounts earlier this year.
The agency has 6,000 staff in 72 countries, some of whom will be moved with accounts to their sister agencies.
