In a DWP Pensions Green paper, mention is made of Inkfish’s parent company, Domestic & General, who estimate that their policies of employing and keeping older workers have reduced their recruitment costs by 50%. 

“We have a high retention rate among our older workers. They add balance to a team, bring excellent life skills, and also reduce our recruitment costs with a resultant direct effect on our bottom line.”

This specific reference is on page 104 of DWP Pensions Green Paper: The Department for Work and Pensions - Simplicity, security and choice: Working and saving for retirement.
