You don't have to be sick to get better. With HappyAtWork, we offer collaborative agreements in occupational health and safety services that prioritize employability. Our approach is positive, proactive, and always focused on opportunities, both during and before absences.


We support absenteeism together with you and your employee, and actively work to prevent it. Because people are your organization's capital. That's why we always look at what can be done, both within an ongoing absenteeism case and when strengthening employability in the workplace.


We offer three different connections for SMEs. The quality of our service is always the same; the difference lies in the size and content of the package.


We offer customized solutions for large organizations. We'd be happy to discuss a suitable solution with you.
