Employers have been urged by the government to invest in their staff whatever their age.
The Department for Work and Pensions (DWP) has advised employers to invest in training for their staff every three to five years.
"Most skills have a three to five year shelf-life therefore employers need to invest in all their staff, whatever their age, to keep them fully trained," a spokesperson for the department said.
Furthermore, small to medium-sized enterprises should consider offering flexible working options to those members of staff who request retirement.
In reference to age discrimination in companies, the spokesperson added: "Tackling discrimination helps to attract, motivate and retain staff."
The DWP also claimed that many businesses have an "outdated" view to recruiting staff that does not meet legislation standards.
Regulations amended in April this year state that older workers have the same rights as younger staff, particularly in reference to redundancy pay and unfair dismissal.
