I hate people who are not transparent about wages or people who gatekeep skills.
Ask a union guy how much rhey make they tell you their total package.
Ask a guy at a wholesaler how much they make they refuse to tell you for reasons???
Read on reddit how much x trade makes and they always post some insane number without mentioning where they work, if they own their own company or if they work a shit load of overtime.
If we were all transparent in our own trades about what we do and how much we make we could help others who are trying to advance in their trades. Probably not targeted to people here but I've helped countless apprentices find work and will always stick out my neck for people who try to better themselves by getting a skill because I was in their shoes once when I was desperate to learn a skill that noone could take away from me.
At that time my journeyman took a chance and because of it I'm not longer working some general labour job.
The worst personally for me was wanting to learn hydronic heating but getting pigeonholed into service plumbing and wasn't allowed to go on any heating calls. Really stunted me developmentally. Now I'm in the 16th year as a plumber and jumped to a company finally willing to train me in areas I want to be trained in.
Tldr; join a union if you can.
