Facility Maintenance is one of the occupations that have a dwindling population, not due to less demand but an aging factor. I think the last time I read on it the avg age is pushing 50. Due to the varied hats one must wear, electrical, plumbing, boiler, HVAC, pressurized gasses for medical use, etc., many young people don't look to get into the field. They would rather get the one hat and get a job. Anyone that is looking to get a job I think this one has many opportunities, but please correct me if I'm wrong. At least in my area it does. At the hospital where I work in Mpls most of the maint. guys are in their 50's, need fresh young blood.
