Class and economic background plays a significant role on an individual's career progression, compared to any other diversity characteristics, according to KPMG research
The consulting firm looked at the career paths of more than 16,500 partners and employees at the company over a five-year period.
Together with social mobility experts at the Bridge Group, KPMG revealed that class background had the biggest effect on an individual's rates of progression within the company.
This was measured through examining the average time it took employees to be promoted, taking into account their gender, ethnicity, disability, sexual orientation and socio-economic background.
Individuals from lower a socio-economic background took on average 19% longer to progress to the next grade when compared to those from higher socio-economic backgrounds.
