It’s certainly not for everyone, but if you’re cut out for it there’s a decent living to be had. Yes, there are some bad employers (which industry hasn’t got them?) but generally it’s more than ok.
As for the negativity, I question the reasoning behind someone going to work every day doing a job that they clearly dislike. Why not train to do something else? The thought of getting out of bed every day to be miserable doesn’t sit well with me. In any trade or profession, there are confirmed moaners, and this industry is no different.
So make your mind up. If you think it’s for you, give it a crack. You may never look back.
