WOTC - Retrenchment benefit

I asked this question in the Wisdom of the Crowd:

Should companies be required to provide retrenchment benefit?

Here are the responses: (42 Votes)

79 % - It should be mandatory after the employee has served at least 5 years of service.
10 % - It should be left to collective bargaining between the employer and the trade union.
7 % - This is not necessary as the employer has contributed to CPF.
5 % - A non-bargainable employee can negotiate for it as a term of employment.
