High-profile strategy consulting firms that advise clients to increase the diversity of their workforces and leadership teams have gender pay gaps that exceed their industry and are up to double the national benchmark.

McKinsey has a median gap between men and women for total pay of 38 per cent, Boston Consulting Group’s gap is 35 per cent and Bain’s gap is 31 per cent. This compares to median gap for total pay of 26 per cent for the professional, scientific and technical services industry and the national gap of 19 per cent.
