Well i've never seen the discussions you are talking about so i
can't draw my own conclusions.....
But assuming they are doing their job and put up an effective
stand during such discussions, the big question remains if it is
effectively affecting Singaporeans at the ground level? And if it
isn't why? Govt policies? Employers relocating?
P.S. link the discussion i'd like to read it 
I assume u refer to my post.
1.Labour union in SG represented by NTUC.Dunt think people in SG
have been and are still highly controlled by ISD and secret
police.No one know better than LKY the power of labour
union.He was a young and voluntairly legal adviser to then
unions in 1950's ,carring a rare double honours in Laws fr
Cambridge or Oxford!!He came to power with the aids of unions to a
great extend.Unions leaders and members were and are still human
beings.They will crash with political leaders if their live
suffer.
2.who say Union in SG is powerless?In 1980's,SIA Pilot Union was
so strong that LKY had to come out and said he would wind up SIA if
the pilots did not return to negotiating table.
Then u know the famous SIA union leader ,who was SG
PR from Malaysi,whose PR status was cancelled. Ryan
Goh Yew Hock,is a Malaysian.

3.NTUC
Fairprice Supermarket etc help to stabalize prices in
SG.
U ask how HK people feel about the two Super market chains in
HK_------Park N Shop and Welcome,run by greedy owners!Ask
Malaysians why they always short of important foods stuff near
CNY,but not near other festivals!!
NTUC has a political duty to make SG people happy.LKY and their
old and new gurads know SG citizens are human.
Like Chinese saying go,''Water can hold ships,also can flip the
ships!!''
We are not prisioners of Singapore Prision ,nor patients of SG
hospital!!
The little red dot passport and the eduaction can help us
migrate anywhere easily,anytime and anywhere.Quota for
Singaporean or ambassy in SG always open.
