It's important to look at this change in its true form. This is not a savings. It's not as though employees are filling up backpacks with cans of soda, going to the overpass, and chucking cans at cars. It's not as though $600k in soda is rotting away somehow because it's being improperly stored. No, this is a benefit provided to employees as a condition of their employment. Cutting that benefit is equivalent to a salary cut.
Management is taking money away from its employees and giving it to themselves and the shareholders.
