You may use these letters if you wish. However they are suggestions only and do not constitute legal advice. We recommend that you take legal advice about your position at the earliest opportunity to protect you.
You will need to use the letter that is relevant to your situation. Some businesses are statutorily required to ask their employees to wear a mask, but if you are exempt you do not need to wear one.
Hence where you see the title “statute” or “no statute” in the heading, the former relates to business that are caught by the statutory laws and the latter relates to those that are not. Please therefore check to see if the business you work in falls into the category of being bound to ask their employees to wear masks, or not before using the letters.
