Not sure why some "hate" the union; same as why some "love" the union. I don't think either emotion is healthy for a functioning representative body.
Members should strive to stay engaged with the union as much as possible. I interpret this as providing both positive and negative feedback to your representatives; attending LEC meetings -- especially when a critical decision is brewing; vote, or submit proxies; read the communications, and provide feedback. Our TA had tremendous membership participation, as did the recent C081 recall vote.
I understand that constructive criticism can be interpreted as "hate," but I would take that any day over apathy and non-participation.
