The company's sick leave policy says:

This company’s sick leave policy applies to all our employees who have been with our company for more than six months. Our employees can take sick leave only when they want to recover from a sudden illness, accident, or injury. They can use up to 10 days of sick leave for these purposes per calendar year.

Upon completion of each 12 month period of employment, employees will receive 3 additional days of sick leave for every completed 12 month period of working for the company. Unspent additional sick leave days cannot be transferred to the next 12 month period. For example, an employee who has worked for the company for 10 years would receive 30 additional days of sick leave, or 40 in total.

Keep in mind that employees who become sick should either use their sick days or work from home to avoid spreading illnesses.
