Sorry to say, but you don t actually work for Subway, you work for the owners of the franchise (whatever the issuing name is on your paycheck). It s a completely different company. That email address provided by Antony is for people who are actually employed by Doctor s Associates Inc at the Subway HQ in Connecticut. If you can t work things out with the owners and they aren t doing anything illegal you are out of luck.
