A fair debate has to occur on all parts of the "Tentative Agreement" including the CTI. Just having a "no side" on the CTI issue or other issues isn't a fair democratic debate. In any CUPW local, members can be found that support the "yes side".
If the union is truly democratic, it would see that both sides are heard equally on any issue. There should be a committee that supports the "no side" and a committee that supports the "yes side". Union dues would be equally distributed to promote the views of both sides. This happened at the National CUPW Level when "vote no" NEB members expressed their views on the national website.
Where the local executive is predominately "no" orientated, the yes members should also have a voice to express their views to undecided local members. The 5% of those who attend union meetings do not speak for everyone. The silent majority pays union dues and they should have a platform for their views as well.
