Light switch grounding requirements

I live in a very nice 6 year old rental duplex.
One of the 3 way lighting swtiches was bad so I just went to the store and bought a new switch and replaced the old one.
To my surprise, I found that none of the 3 each 3 way switches in the 3 gang box had grounds on them.
It's a wonder this place passed inspection.
I thought that was a no no in a place this new.

This might have pre-dated the grounding requirements or the box might provide the grounding if metallic.

You should not be making repairs in a rental. Have the landlord contract a licensed contractor due to liability issues.

Pre dated in a 6 your old home? I don't think so!
And the box is not metal either.

Does the box have a metal strip where the switch screws (yoke) attaches to the box?

No. There is no ground wire in the box at all and the box is the plastic type.
No extra wires whatsoever, only the 9 wires for the 3 each 3 way switches.

Wait....There is no ground wires? Could you take a picture of this box? The only way you will not have a ground wire present in a 6 year old building, is with a metallic wiring method such as EMT, or AC/MC cable.

None at all present.
No emt and the wiring had some of the cheapest plastic feeling insulation on it I have even seen.
And I worked in the electronics trade for many years before retiring working on the subs.
Really a nice rental but now I wonder what else I cannot see.
I have seen some shoddy work in older buildings I have been in but this is really strange.

Question. What color is the outer sheathing on the NM cable and size are the conductors, #14 or #12?
