I do understand, but in reality this electricity nor anything else is free. Tax incentives are paid by the working class (all tax payers). The employer is paying for the electricity, since it is cheaper for he or she to pay for the amount of electricity given to you "free" for a few hours, than it is to significantly increase your wages x 8 hours per day. Most companies have work-incentives, but every incentive is taken into account down to the "penny" by the accountants, since the company cannot exist long under a loss of revenue.
It is the same for the healthcare offered to the employee by the employer. Someone has to pay for it. The simplest way to understand is by breaking it down to the individual level: how much you earn/how much you spend. If you spend more than what you earn, then somebody else has to pay for some of your living expenses. You can see this by the great number of "green technology" companies that pop here and there and then disappear a few years later. Government grants (tax-payers' money) alone can't sustain a private sector company.
I’m aware electricity isn’t free and the employer is absorbing the cost, I wasn’t suggesting it was some special case. The company my wife works for make £200m profit a year and turnover close to £500m. They have 12 directors, one of which is my wife and she gets a company car with charging at no extra cost to her. She technically pays £700 a month for the car as that is her company car allowance, not that she would see that money as it is deducted as part of her package. She pays £20 a month in tax for the car. The company letting her have £10 a weeks worth of charging on site is a drop in the ocean for them. They’ve just bought three Porsche Taycans for the chief officers of the company so I think the main motive is investing in the people that make the business a success. Yeah it’s not free ultimately, but the people receiving the benefits aren’t necessarily paying out of their own pockets for it, that was my point.
