STEM Returners was created as a pilot project for a small number of engineering companies in 2017 in response to a growing skills gap at the mid career level and a lack of progress in diversity. We have now successfully returned over 190 engineers across the UK to their prior profession. We have worked with like-minded employers, small and large, to remove the barriers that returners face, tackle unconscious bias and challenge a broken recruitment system that undervalues experienced hires due to a career break. Overcoming barriers and creating opportunities for returners is why we exist and increasing diversity and inclusion within STEM is at the heart of what we do. Of all of our returners, 96% have been retained in permanent positions, 46% are female (compared to an engineering average of 10%) and 34% are from minority ethnic backgrounds (compared to an engineering average of 6%).
