This sort of thing is a real pet peeve of mine:

Singapore, famous for its spotless streets, is stepping up its campaign against filth in the restroom with a training program to boost the status and skills of the city-state's toilet cleaners, a newspaper reported Thursday.

More than 50 toilet cleaners will be promoted to "restroom specialist" upon completing the three-day pilot course taught by Japanese experts in the latest toilet technology, The Straits Times reported.
...
"Cleaners have low morale and low skills," the paper quoted Jack Sim, the World Toilet College's founder, as saying. "We want to professionalize them and teach them to be proud of their jobs."

Nothing boosts morale like calling someone a "specialist", "engineer", or "technician".  They scrub toilets!  I really don't think that giving them a new fancy title is going to make their job more fulfilling, or make it any less smelly or disgusting.  It's the job, not the title, that makes it fulfilling.  Don't kid yourself into thinking this will make them feel better about what they do.  And certainly don't bring all real engineers, specialists and technicians down a notch by using those terms where they don't belong.
