Love and hate mine.
Maintenance engineer. That covers everything from clearing blocked toilets to working on 3 phase electrics, fault finding on machinery, breakdowns, servicing, admin, periodic tests such as emergency lighting etc etc etc. The myriad of things that can go wrong in a big factory always interfer with the day to day stuff you have to do, no day is ever the same, very few days are boring.
I rate my day as one of either...easy (rare)...no stress busy ( the best kind)..or stressy busy...where youre very very busy, cant resolve stuff, day to day stuff has to be put to one side but it's still in your head, thankfully those days only rear up maybe a few days a month but you do go home somewhat stressed.
Time management....impossible. your ass belongs to whoever the next job happens to come from?
