Is CLAC a REAL Union???

I am writing from Edmonton, Alberta, Canada.

We have up here what I consider a BOGUS Union called CLAC
(Christian Labor Alliance of Canada). It apparently is connected to the Dutch Reform Church. It is what I believe a union of convenience. That is, a union half-heartedly representing its members, but absolutely in partnership with the employers.
Is there such a union in the USA?? or is this exclusive to Canada?

Thanks for your time.
