Re: looking for new help
Read the resume, call the previous employer(s).
Check driving record, interview candidate.
Ask open ended questions. "What size GEC do you use on a 200Amp residential service?" "How about a commercial service?"
What kind of work will these people be doing? Ask your questions in that regard. Remember, hiring somebody is like getting married during the first date.The divorce can be messy.
Definately let them know you have a probation period of XX days. Mine is 90. During that time, you can be let go (fired) for anything.
If you belong to any associations-ABC, IBEW--contact the office for legal advice on what NOT to ask. (Age, race, creed, sexual preference, disabilities, illnesses etc.) You can ask is there is anything that would prohibit you from doing this type of work.
Good luck!
