I'll hawk the company I work for...
PG&E is hiring. Like many businesses they have an ageing workforce. Go to WWW.PGE.COM
to see what available and feel free to PM me if you have questions.
Typically the jobs are in the geographical service territory. That is about 3/4 of California. Eureka to the NW, Burney to the NE, Santa Maria to the SW, and Needles (at the Aridzona Border) in the SE.
There are Jobs out there.
Update: I retired in 2011. Only advice now is go to the website.
