I'm making good progress towards getting my current employer to, at minimum, install a few "locked" 240v outlets that company EV drivers can use for a modest fee (pricing details are still in the works but it looks like they just want a "token" payment).

The thing I'm really not sure about is if I should specify the TYPE of 240v socket?
I feel like I see NEMA 6-20 (3 wire, 240v/20amp) fairly often, but it seems like I also see NEMA 14-30 (4 wire, 240v/30amp) around.

Any thoughts?

If you can, why not suggest 14-50 outlets rated for 50 amps (capable of charging an EV at 40 amps continuous load.) The 14-50 has become the de facto lingua franca (universal language) of EV Level 2 charging.

If there is a discussion about what to charge for use of the outlets, a 20 or 30 amp circuit would be easier to justify for a 'minimal charge' than a 50 amp circuit where someone could actually draw a few dollars worth of juice from in a short time

My 'favorite' 20 amp 240 volt outlet is the L6-20 because it's a small twist-lock and whatever you plug into it will stay connected and not fall out of the socket with use. It also has larger blades to make the connection, so it's less likely to eventually have a high resistance connection. I have several of these outlets in my garage (3 electric cars) and I have adapters and extension cords with L6-20 connectors. You can buy the plugs and sockets from Lowes or Home Depot and they're not expensive. Another benefit to using them in a public place where you don't know who might be using your electricity it that it's not so common that most unauthorized people would be able to plug into your power

I respectfully disagree. If you install a 32 or higher amperage charging capability then more vehicles will be able to use the charging station (well, not the Volt except for the 2019 with the 7.2kW onboard charging feature) but many other EV and PHEV. Each EV parking/charging space could service 3-4 vehicles in a workday instead of 1-2.

I agree that getting NEMA 14-50 outlets would be swell, but this is a very uphill battle I'm fighting.
I know for an absolute FACT that they will not buy/install any EVSE units.

At present the concept is a row of covered sockets, and the "ev club" drivers would be issued keys or combinations to the padlocks for the covers. Heck I've been struggling with the concept of having 2-3 parking spaces marked "EV ONLY".

Quite a change from my previous employer who ran wire to the far edge of the parking lot (thus circumventing the "preferred parking complaints issue" and had 6 free Clipper Creek ev stations and was planning on putting in 6 more.

Yep, you don't want to get too greedy. Don't ask for the moon and the stars when you're lucky to get an orbit around the earth because you might end up getting earthbound.
