Having double the amount of reliable charging stations is also key to bringing people on board.
This assumes you need workplace charging. Also, reserved parking must be a paid parking system or the IRS will claim you received renumeration in the form of free electricity that you have to include on your tax return.Yah, The key to workplace charging is reserved parking and a forest of level 1 EVSE.
It also addresses the inevitable, "Where's my free gasoline!!?" from other employees.So charge for it. For those for whom it's peace of mind will cheerfully cough up $15 or some other reasonable fee. Those that don't need it won't and that's fine too. It takes all the controversy and insecurity out of it.
