Trying to join local one

Trying to join local one but need to work a ton to actually get in. How consistent is the replacement room for those trying to join? I have every tool imaginable for stagehanding, OSHA-30 and MEWP certifications and want to work. I started one job with local one as a non card holder but am worried the hours won’t be consistent enough to make the income requirements. Trying to break away from non-union stagehanding. I have experience working on live television and live events
