Professional development

Working at Thommessen means working with leading Norwegian and international businesses. We are at the forefront of new developments, which demands much more than legal expertise alone. Commercial law is not about rules and regulations; it is about understanding the bigger picture. It requires you and your team to analyse issues in context and to genuinely understand the challenges our clients face – from a commercial, social, political and global perspective.

The ThommessenSchool (our training portal) and our project model are both crucial tools for facilitating effective collaboration within our teams on exciting projects, and ensuring continuous competence development for all team members.

"We need to be honest about the fact that being a lawyer in a commercial law firm is not a nine-to-five job. We charge high hourly rates, and availability is part of what our clients pay for. However, there is a crucial difference between working long hours to successfully complete an exciting project and working long hours due to poor time management. An advantage of working at Thommessen is that we work in teams. Well-composed teams whose members complement each other enable everyone to have a life outside their professional commitments, even during hectic periods."

Work environment

To collaborate effectively, it's essential that we enjoy each other's company. Therefore, we are committed to creating a friendly working environment where everyone is seen and valued. We celebrate progress together and support each other when facing challenges.

As part of TeamThommessen, you have the opportunity to participate in several social activities, including our monthly after-work gathering, summer parties, Christmas parties, company trips, leisure courses, and training sessions organized by our sports club. Here, you can browse through some of the recent events at Thommessen.

Diversity, inclusion and equal opportunities

We are actively seeking to create a firm characterised by greater diversity. At Thommessen, everyone is given equal opportunities and is encouraged to be themselves at work, irrespective of background, gender, religion, ethnicity, and sexual orientation. We want everyone, including newcomer to Thommessen, to feel that they can contribute with their true selves.

Our strategy includes specific targets for increasing the proportion of women among our Managing Associates and Partners, as well as goals to become a company characterized by greater diversity. To reach our targets, we have introduced a number of measures related to recruitment, management training, and flexibility for staff with small children, among others.

At Thommessen, we have a dedicated Diversity and Inclusion Committee (pictured below) that contributes to creating a workplace that promotes equality and diversity, and has an inclusive work environment where everyone feels seen, heard, and respected for who they are. The committee consists of committed employees who want to contribute to Thommessen's environment and culture and is an important partner for the management in achieving the company's goals related to equality, inclusion, and diversity.

The committee is also responsible for internal activities and campaigns related to diversity, inclusion, and equality. Throughout the year, events and internal campaigns are organized – including those related to celebrations such as International Women's Day, Pride, and World Mental Health Day.

Well-functioning businesses are sustainable businesses. As advisors to both Norwegian and international businesses, we want to guide them towards future-oriented and sustainable solutions.

Sustainability intersects with all industries and aspects of business. Sustainable development will be a key priority, irrespectively of whether your speciality is tax, renewable energy, financing, public procurement, shipping, or another field. Therefore, we took an early lead in establishing an interdisciplinary sustainability group with a specific sustainability and climate risk remit. This group consists of partners, attorneys and associates from various disciplines.

In addition to working with our clients to advance their sustainable development agendas, we have an internal green committee, ThommessenZero, which actively seeks to reduce Thommessen’s greenhouse gas emissions and other environmental impacts.
