Some government agencies have put out recent tenders setting limits on the age of security guards to be hired, even though this is in clear violation of anti-discrimination hiring guidelines.
Most of the agencies capped the age of guards at 55, below the statutory retirement age of 62.
They have since rectified what they said was an "oversight" and stressed that the tenders eventually did not stop them from hiring workers older than the age limit.
Last December, the Ministry of the Environment and Water Resources (MEWR) awarded a $704,000 security services contract for its headquarters in Scotts Road.
It stated in the contract that guards deployed by its contractor should not be older than 55 years. Supervisors have to be below 50.
In January this year, the Civil Aviation Authority of Singapore (CAAS) signed a $64,000 deal with a security firm to guard the Singapore Aviation Academy.
The age ceiling for guards was 45.
The Ministry of Foreign Affairs (MFA) is currently looking to hire a firm to guard the Asia-Pacific Economic Cooperation Secretariat and Asia-Europe Foundation buildings near Pasir Panjang Road.
It put out a tender last month stating that the security firm has to hire guards between 25 and 55 years of age.
