Union or non union?!

I shared a post here some time ago about being a young African-American man living in Las Vegas. I'm currently employed in the hotel industry but aspire to transition into the trades, specifically to become an elevator technician. My goal is to acquire a valuable skill while also increasing my earnings to boost my savings for a potential home down payment. There's a non-union job opening for an electric journeyman at an electrical company, and they are starting their recruitment now. Conversely, the union-based electric journeyman position will begin recruiting in May. I would appreciate insights from anyone who has experience with both union and non-union work.

Thank you for your time and replies!
