How does the Opening Doors campaign promote social mobility?

The Opening Doors campaign is primarily focused on those groups who are disadvantaged in the labour market because of their background or life experience. 

These include ex-military, people with convictions, people experiencing homelessness, long-term unemployed, refugees, young people, older workers, disabled people, neurodiverse people.
This list is not exhaustive, and a business may identify other groups it would like to support, including those facing intersectional barriers relating to race or gender
