Something in the energy field, providing power, should be secure. Something in the repair field, mechanic-HVAC-electrician-plumber-carpentry, should be secure. Medical field should be secure. Veterinary and pest removal and exterminator jobs should be secure. Teaching field should be secure. Clean-up field, garbage removal-recycling-water and waste management-janitorial-etc., should be secure. Supplying needs fields, including food and clothing, should be secure.
Working for the government, whether city, state or federal, is usually very difficult to get laid off in. They tell me that my job is considered a state job, as it is state funded, and it's difficult once past the initial 90 day period to fire someone and I work at a community college. The pay is pretty low as I do janitorial, but the benefits is pretty damn outstanding. I'm thinking of going into automobile mechanics though.
