To celebrate International Women’s Day and this year’s theme, , we’re highlighting how mentoring forms an integral part of our Empower Programme, a career development programme designed to support our women talent in reaching their career goals.

The programme includes holding mentoring circles to provide space for learners to come together in small groups, explore ideas and gain different perspectives. By giving their time, our mentors support women to overcome personal and professional barriers to progression and inspire gender equality.

Asha Mistry, a Principal Environmental Consultant who recently completed Empower, explains the importance of mentors on the programme:

“Being on Costain’s Empower Programme has helped me learn what my strengths are and to embrace them. It was inspirational hearing from my fellow cohort and senior leaders on how they overcame challenges both professionally and personally.

“Mentoring circles were small groups which made it easier to have more in-depth conversations where we would focus on topics that were specific to us. I’ve gained the confidence to say “yes” to more opportunities that come my way.”
