Many are planning to do exactly that, at a profit too!
First of all, most businesses will not allow freeloaders to charge their cars in the parking lot. Not only employees can do it, but also any member of the public. And businesses pay pretty penny for electricity.
But there is another interesting aspect. If a business provides some free (or nearly free) service to the employee then IRS will want to know more about it, since it's an unreported, untaxed compensation. No business will be willing to put its neck under the IRS's axe just to please a few employees.
So in the end there will be chargers with meters, and you need to swipe your access card to get it started, and the cost of the energy will be deducted from your paycheck.
As more and more EVs show up on the roads, energy companies will be able to take control of the situation and raise the prices to the market levels. This means that many owners of those cars will not be able to afford charging of their vehicles! The market price is not the price which everyone can afford; it's the price that results in maximum profit.
Today PG&E indeed has a rate schedule for EVs. It is time-dependent, and it can change at any time. We can't be sure that the price of gas will always be $3.20 or whatever it is today, but similarly we have no reason to believe that electric energy will be always sold for $0.10/kWh at the lowest tier.
