01 / THE WORK
Psychology that connects the person with the wider business system.
I’m Ilia Tsa, a business psychologist and industrial-organisational psychologist with a background in organisational psychology, career counselling and evidence-based psychotherapy.
Some challenges appear personal but are shaped by a role, a team or an organisation. Others look operational but are sustained by stress, avoidance, conflict or deeply learned patterns. My work examines both.
In the UK this field is often called occupational psychology; across Europe, work and organisational psychology; and in the US, industrial-organisational psychology. Business psychology brings these perspectives into practical work with professionals and organisations.
