Employers pay contributions to the employee's NI. I don't know the exact ratios, but it's non-trivial. I threw PAYE in there, since NI and PAYE tend to go hand-in-hand. Looking at it again, I probably muddied my explanation somewhat. Starbucks aren't preaching to their employees, but they are trying to claim moral credit for paying a tax that's not worth their time to get out of paying.
