Culture / Diversity & Inclusion

We are committed to fostering a culture that is all about creating an inclusive environment, accepting of every individual’s differences, enabling all employees to achieve their full potential and as a result, allowing our business to reach its fullest potential. If we value each person’s differences, then we are allowing each person to contribute their unique experiences, which can have an extremely positive impact on work, other employees, motivation, productivity and client experience.

As Northern Ireland’s leading law firm, we are committed to maintaining a truly inclusive workplace where everyone feels valued and respected because of their difference – a place where every employee can be themselves so they can reach their potential and help us achieve our business goals.

Our vision is to have a respectful and supportive workplace that enables us to attract and retain a diverse workforce that represents our clients and community.

We currently hold the Diversity Mark Bronze award which demonstrates that for us, diversity and inclusion is not just about ticking a box, it is about taking action. For example, we offer diversity and inclusion training for all staff and our Diversity and Inclusion Committee leads a range of initiatives across the firm. 47% of our Partners our female, including our Senior Partner.

We have three key goals:

  1. Workforce diversity – recruit from a diverse group of candidates to increase diversity among the workforce that represents our clients and the wider community
  2. Workplace inclusion – foster a culture that encourages collaboration, flexibility and fairness to enable all employees to contribute to their potential and increase retention
  3. Sustainability and accountability – identify and break down barriers to full inclusion by embedding diversity and inclusion in policies and practices and making sure we are accountable for delivering results.

We have signed up to the Mindful Business Charter, which intends to remove unnecessary sources of stress and promote better mental health and wellbeing in the workplace.
