My thoughts exactly Gg
While I DO see it as a drastic step, it is also very clear that it is entirely voluntary and sits alongside the other BRP options. For those unable to consider PT or VUL, but who do wish to do something, as allowances will still be paid, it's another (slightly less painful) option to at least consider.
Just to quickly remind people:
1) it's voluntary
2) can be 1 to 4 weeks
3) only basic salary is affected, allowances etc ARE paid
4) deduction can be spread over 3 or 6 months
