YUM! Brands is committed to conducting its business in an ethical, legal and socially responsible manner. To encourage compliance with all legal requirements and ethical business practices, Yum has established this Supplier Code of Conduct (the "Code") for Yum's U.S. suppliers ("Suppliers").

From the "Tacobell.com/ourcompany" website.

Maybe someone should suggest they investigate another "Code"...

If you wanted to go "head to head" with the maintenance electrician (if he threatens your employment again) you might want to consider submitting pictures of his work (approved or performed) to his licensing Authority as a complaint.

However, notice the phrase I used above - his work (approved or performed). Here in northern IL (as in most AHJ's IIRC), an EC is responsible for work he performs or "signs off" on, that others have performed in his stead, or under his supervision. If he is saying the work at "worksite x" is up to Code (the National Electrical one [Linked Image] ), then he has to answer for any discoveries by an AHJ that it isn't.

BTW - check your store's local EC - here in my northern suburb, the minimum conductor size for any commercial or industrial occupancy 110 circuit is 12AWG...
