Winsløw takes it for granted

Diversity, work/life balance and pro bono are buzzwords describing what we at Winsløw take
for granted.

Since the foundation in 2005 have made it a point in order to render our clients with the best
possible legal advice, we need to present a strong team of competent and dedicated lawyers.
And those we are able to attract by being a attractive workplace for both men and women as
well as being a company our clients would like to be associated with. At Winsløw we are 3 male
and 4 female partners. Others call it diversity. We take it for granted.

It is part of our DNA that everyone at Winsløw engage in both our client and the team who is
our company. To cooperate in delivering specialized counselling within the areas of real estate
and construction law works best when our team is healthy, well-rested and in good shape. Thus
exercise during weekdays, i.e. pilates, running activities and social events for our employees
combined with fair working conditions for everyone at Winsløw is a matter of course. Others
call is work/life balance.

At Winsløw we contribute to society with a work effort that is not measured in currency. Each
year we devote many hours of voluntary work where our expertise as lawyers make a
difference. Our voluntary work ranges from evening work with free legal aid, board services in
foundations and societies, participation in preliminary bill preparations and working with
interest groups in both Denmark and internationally. Others call it pro bono. We call it a matter
of course.
