Mine provides it for free and I use it. Good stuff!
It's a huge perk. Such employers are considered "cool" and "in touch" in the Bay Area for sure. Makes for a decent recruitment tool too; candidates who come for on-site interviews do take note of the EVs charging out front.
Actually, the one month last summer that I had to charge exclusively at home - when I moved house and before my employer had setup all the charging stations - my tiered rate plan with the utility put me all the way in the top tier paying over $0.35 a kWh; a utility bill of over $400 was, well, a shocker!
My savings - without switching to a time-of-use plan and the accompanying inconveniences with watching the clock for non-EV electricity use - are atleast $200 per month so, it's definitely a great indirect monetary perk from the employer.
Yep. I suspect that for some candidates, it can help w/influencing them to come aboard. It means they're more likely to be able to drive a vehicle eligible for CA white HOV stickers w/o breaking the bank for a car w/lots of battery capacity (e.g. Model S or Rav 4 EV), and save time by taking advantage of HOV lanes, if they commute during rush hour.
And even w/o the HOV benefit, yep, for me, I almost always stay within tier 1 of PG&E (known for high rates). If I charged only at home, I'd go well beyond tier 1 and probably into tier 3, where it starts getting real pricey.
Those who have only lived in places w/cheap electricity (e.g. WA) have not experienced how bad it can be in some other parts of the US. PG&E is notoriously bad, but folks in Hawaii have it really bad (since most of their electricity comes from oil).
Value to me is $0.
Not worth the hassle of adapters, cords, and cards every morning, plus needing to go out in the middle of the day to move my car or see if someone else needs plugging in, to save $1 a day.
I don't need adapters nor cords w/my Leaf. Our stations have J1772 handles and my Leaf uses J1772. Card stays with me.
I normally just start charging late in the day (4 or 5 pm or even later) since I leave late on most days. By that point, numerous EV spots are empty.
It also enables me to make further trips after work than if I charged only at home. My commute is 12 miles 1 way and when your EV only has an EPA rating of 75 miles... And, if I made a very long trip after work and then charged at home, my overnight charging at 120 volts (don't have any 240 volt charging solution at home), I wouldn't be at 100% by the time I needed to leave for work again.
We also recently started an EV valet service. Some other Bay Area companies w/EV charging have EV valets.
We kinda had to do valets anyway because our parking was getting too full due to our growth and not being able to expand to new buildings until next year.
