Is it worth being a CPSU member?

I’ve been a union member for the past 6 years. But I’m reconsidering if it is actually worth it. When I worked for a government agency I had a number of issues and we also had regular union meetings. But I moved to working for an actual department about 2 years ag and I’ve not been invited to a single meeting and have not needed to contact the union once, even through a clause 11. Considering ditching the membership.
