A super-union is getting closer to fruition.

Canadian Auto Workers delegates voted unanimously to merge with the C-E-P labour union.

Delegates with the Communications, Energy and Paperworks Union will vote on the merger in October at their meeting in Quebec.

If it's accepted, it'll mean one union representing 300-thousand workers from about 20 difference industries.

The proposed merger comes amid a falling unionized rate. Last year, just over 31 per cent of Canadian workers belonged to a union which is down 2.5 percentage points since 1997.
