Chartered Institute of Personnel and Development held an online poll of 255 employers to find that the default retirement age prevented each fifth employer from offering jobs to candidates aged 65 or older. Actually it has caused these employers to miss out on talent.
Statistics shows that older workers are more loyal and reliable, rates of their sickness absence is lower and in general they perform better. Abolishing mandatory retirement not only allow older workers to decide how and when to stop working, but would allow business also to benefit from wider range of skilled and experienced employees.
Some employers have already rejected age discrimination and took advantage of the talent older workers brought to the workforce and wider economy from encouraging better management of older workers. Maybe it's time for you to follow their example?
