I don’t have any experience with this union, but I have lots with other unions. There are often work change polls, seniority issues to work out along with grade changes and a bunch of other stuff before moving to external offerings. It’s a long and ridiculous process, especially if you have multiple unions working in the same group. The most I worked with was 5 unions and it took months to ‘get permission’ to hire someone externally. Hell, I wanted to move some machinery to a different building and it took me nearly a year because the union thought it was being done to ‘reduce overhead’ when I was literally just moving it to a different building to give them more room to work.
