What is the policy for employees with facial hair?

Whilst we prefer our employee to be clean shaven. Beards, moustaches and sideburns are allowed but must be kept short neat, smart and clean. If your beard can't be trimmed for genuine religious, cultural or medical grounds or if you are working in a production area such as the kitchen, on fries or the beverage cell, you must cover your facial hair with an approved beard net/snood (This also includes stubble). If you can't cover your facial hair completely, it's not allowed.
