A report by McKinsey & Company reveals that women constitute less than 20% of tech workers in Europe, a decline from the previous year. The gender gap is expected to widen without intervention, particularly as AI reshapes the tech landscape. Women face significant barriers in career progression, with only 19% in tech roles and even fewer in leadership positions. Workplace culture and sexism contribute to women's departure from tech jobs. The report suggests improving workplace culture, setting representation targets, and enhancing mentorship to close the gender gap.
