Garbage operative supervisor?
What the hell is that? You must work in IT.
Perhaps you just meant, "dustman".
This inanity is one of the worst things about working in Informatics, sorry, information technology, to use more syllables and make it sound cleverer than it is.
Actually, it is boring and frustrating and highly stressful for no good reason. It used to be almost fun. Now it is just windows interfaces to badly written systems written by somebody who never, intellectually, got past Janet and John or Noddy and Big Ears. Hours, days, years wasted getting around poorly implemented responses to badly designed solutions to misunderstood, wrong specifications for pointless or dodgy requirements.
The clever, interesting stuff is a minority sport, a small and lucky minority. The rest work for banks, "retail", finance and who knows what, battling through reams of dreadful documents, security, audit, control systems, management systems, nearly all in place to try to overcome the sheer idiocy and irresponsibility of know-all "IT specialists".
I and most other people in this line of work whom I know all advice our children to avoid IT at all costs. Actually, most are reasonably bright and have worked that out for themselves.
