almost impossible,
there is this SAF rule which states Full Time NS men (which is
those serving 2 years one or sign on ones) are not allowed to have
another job outside of it, legally speaking. So even if your 8-5
you cant get a job legally speaking, unless they wanna bend or
break the rules for an exceptional case then good luck to you
!!
Generally it is illegal to work outside, but it is also mainly
dependent on TS's direct superiors; whether they are willing to
bend the rules a bit for him.
Of course, if they are willing to help the TS out, it will be
wise for the TS to keep his mouth zipped over such things.
TS should take 8800's suggestion into consideration. Of course,
he will have to give up all future aspirations which he might have,
but here is when he will have to weigh his future and his family,
and decide which is more important.
