The mental health sector is broad and set to grow, with embedding good mental health habits and wellbeing seen as critical not only in the health sector but in education and commercial business environments too.
Whilst you may well be familiar with some of the therapeutic roles available in mental health - counsellors, therapists, mental health nurses, psychologists - the mental health sector also encompasses jobs in policy and law, admin, communications, as well as broader business functions. Many corporate HR departments now employ someone with responsibility for wellbeing and staff inclusion, which often crosses over with equality, diversity and inclusion or sustainability. You might also want to look at frontline services in housing, debt advice, youth work, community development, substance abuse or criminal justice, all of which involve working with people with mental health problems.
If you are interested in working in this area, then doing volunteer work alongside your degree will help improve your confidence, skills and knowledge of the broader sector.
