Yes I can sympathise with that! No holidays, no Bank Holidays, no sick pay, etc.... Still at least I can work over a grotty weekend & take a sunny (I think I remember those!

) day off in the week - if there's not too much to do....
I know from experience that driving instructor's don't earn the figures in the adverts (well they can EARN that figure, but it's very different to profit!). I always quite fancied being a driving instructor, but I've done enough instructors' accounts to know it wouldn't pay the bills easily.
