Staff at IPG’s former agencies, now part of Omnicom, were set to leave their London headquarters near the Old Bailey for Omnicom Bankside this month following the latter’s acquisition of IPG last November.
Campaign also reported in December that Omnicom had warned employees that requirements to be in the office three days per week would be “increased over time”.
While it is understood that this has not yet occurred, the policy warns that staff in the US who do not comply with the policy will not receive pay rises or promotions and will be subject to discipline, including the possibility of termination of employment.
When Campaign asked Omnicom what the consequences would be for UK staff who did not comply with the policy, however, the company declined to comment at the time.
But how do the other holding companies compare? Here is Campaign’s round-up of all the latest flexible working policies across the new “big six” agency holding groups, and how they compare with the companies’ previous stipulations.
Accenture
Accenture’s office attendance policy is “hybrid” with no set number of days per week on which employees are mandated to be in the office in the UK and Ireland. In-office days depend on client and project needs.
Sohel Aziz, managing director of the UK and Ireland at Accenture Song, said: “At Accenture Song UK and Ireland, we remain hybrid, but we’re very clear on why our offices matter. They’re not places people are mandated to be, they’re centres for learning, collaboration, connection and creative energy.
“From hands-on training and certification programmes to direct access to Gen-AI tools, we’ve built environments people want to come into. We also encourage colleagues, especially those between projects, to use that time to meet new people, build relationships and continue investing in their skills. The future of work isn’t about forcing presence, it’s about creating environments people value.”
Dentsu
Dentsu still applies a flexible two to three days per week in-office policy for its UK employees.
A Dentsu spokesperson told Campaign: “We have a flexible hybrid working approach that empowers leaders to define how, when and where our teams come together to deliver for clients.
“Our people tend to attend our offices across the UK and Ireland two to three times a week. However, many also connect with clients in other locations on other days. At present, continued flexibility, centred around client outcomes, is our priority.”
Havas
Havas also continues to have a three-days-per-week in-office policy.
A Havas spokesperson told Campaign: “For the past few years, the group’s policy has been three days per week in the office, allowing a maximum of two days of remote work, to promote teamwork and creativity, with some variations depending on specific situations.”
Ominicom
Omnicom’s global policy remains as three days per week in the office minimum, but its policies can vary by section, country and agency.
This is despite the holding company informing staff that requirements to be in-office will be “increased over time”, in a policy updated in November 2025.
Publicis Groupe
Publicis Groupe employees globally have been required to return to the office three days a week since January 2024, including a mandatory presence on Mondays and no consecutive remote-working days.
Campaign understands that different Publicis Groupe agencies apply variations in addition to the above rule, with some requiring employees to go to the office four days a week.
Publicis Media also laid off less than 1% of its US workforce due to staffers ignoring its return-to-office policy in October 2024.
WPP
WPP has kept its mandate of four days per week in the office, which has been in place since April last year.
The global guidelines require employees to work from the office on at least two Fridays per month, with flexibility to choose which other days they work remotely. They also apply across WPP’s operations in dozens of markets.
