Dear Ms. Preis,
We think it’d be a good idea if you reread our policy about sick days. You seem to think its more generous than in actuality. Also, please follow standard hygienic practices in order to prevent spreading of any illness. Management keeps getting infected with the various viruses you’re bringing home from our satellite campus (daycare).
We appreciate your time and would prefer you not visiting the doctor every other day. Plus, the stress of your swollen tonsils/random rashes/scary fevers/etc is becoming a little too much for management mental well-being.
