The biggest con is what must these big companies fail to focus on. Money.
If to ask, even if you document measurable results ,that i spent a long time composing.
You are told that other mechanics get the same or around the same pay. Then say no. Going the extra mile everyday, doesn't get you anything . Yes it's pay. We start a little better than market. But don't go up from there. Yes not right. Not we cannot get any overtime to make up for the lack of raise . It forces good mechanics out .
Also they focus way to much on irrelevant things like dei etc .it should be the work you do not what you look like.
