Don’t kid yourself, if you can’t get up to speed in time (need a babysitter to get the jobs done) or you keep making basic mistakes. You will end up getting a “window seat, on the next plane out” (the mining term used for the sack).
Mines are big business, each turning over 100’s of millions of dollars a year. So they need their employees to perform and those that can’t, are let go.
Getting the job is only half the battle. Once on site, the new starter needs to get up to speed ASAP so they don’t let themselves or their crew down.
