CWA is Communications Workers of America. I am a member of NABET, which is associated with CWA. The call was to inform me of union activities and a couple of victories. Not a telemarketer.
These are occasional conference calls for you to listen to their union political activities.
I like their cause. I've listened to some - I'm not part of it and it gets pretty tedious listening to lots of random people give updates on minor activities, but they sometimes have a leading politician guest that can be interesting.
I've stopped listening usually, but listen if you like, get removed if you don't, this is not telemarketing spam.
These folks are very important in the work they do to counter some of the billionares' huge funding to hurt workers.
This is for CWA union members, if you are not a member simply callback and follow the necessary steps. It isn't spam, if you are not or never were apart of this union then either someone who previously had your number was OR the number was entered/given incorrectly. Calm the hell down people.
