Mechanical, electrical, and plumbing contractors need to understand the most since their work goes all over the building and they’re on the project from start to finish.
Drywallers just come in and put up gypsum once walls have been framed and MEP has been roughed in, and then they leave.
Tapers and mudders command my respect, that’ a difficult trade to perfect. Holding up 4’ x 8’ sheets of gypsum and screwing it to studs might be hard work but it’s dead ass simple.
