At the end of 2017, we thought: “How wonderful would it be if, in addition to the ‘Day of Happiness,’ there was also a week dedicated to Happiness at Work. While we spend the majority of our day at work, it greatly influences the rest of our lives. Therefore, more attention to work happiness can make a difference. By declaring the last week of September as the Week of Work Happiness, we aim to put this theme on the map in as many organizations as possible, ensuring that the movement towards more work happiness grows for both organizations and individuals. Work happiness should be the most normal thing in the world, and that’s what we strive for. The idea is catching on all over the world, by now, the idea has been adopted in 50+ countries. Do you want to know which countries are participating? Check out the website of the International Week of Happiness at Work.

About Maartje and Fennande

Maartje Wolff and Fennande van der Meulen founded Happy Office ( in March 2015 and help organizations with transformation processes towards more work happiness, both top-down and bottom-up. “It is our mission to put work happiness on the agenda of as many organizations as possible, both domestically and internationally. Ultimately, it is especially about taking action, changing behavior and culture. Therefore, we help leaders and employees change (organizational) behavior and build a work culture where work happiness is central. We do this by working with organizations and teams to formulate principles (purpose, values, and behavior), create action plans, and assist with designing and implementing interventions. Our services include developing and setting up programs, training sessions, workshops, and tools. Our principle is to let people do it themselves. At the beginning of 2017, we developed and launched the Training for Work Happiness Specialists, which has been available online since early 2020.

In September 2020, their first book, The Happy Office Manifest: The Pillars of a Positive Work Culture, was published by Business Contact. In 2022, the book was released in the USA under the title The Happy Office Manifesto.

Maartje and Fennande have an academic background in management, marketing, communication, and organizational culture. Additionally, they completed the Executive Program ‘The Return on Happiness’ at Erasmus University, the Team Coach Happy Working training by Onno Hamburger, and the Happiness at Work Expert training at the Woohoo Academy in Copenhagen.
