In S'pore, if one is still unemployed 6 months after being laid off, he is considered retired or no longer interested in re-joining the workforce. We know that a PME older than 45 years of age may take up to 2 or more years to land another job that is comparable to the one he lost, so 6 months is far too short a time period to label someone as no longer interested in looking for a job, and remove him from the list of unemployed. 

In Singapore, a person is counted as unemployed if he or she is

(i) not working during the survey reference week, but is
(ii) actively looking for a job in the last 4 weeks, and
(iii) available for work in the next 2 weeks.

This includes persons who are not working but are taking steps to start their own business or
taking up a new job after the reference week.

There is only this 4-week rule about 'actively looking for a job'. Nothing about 6 months. Any link to this 6-month rule you mentioned?
