WOTC - Require MC for sick leave

I asked this question in the Wisdom of the Crowd:

Should employees be required to get a MC for sick leave?

Here are the responses: (47 Votes)

38 % - It is better to allow the employee to have up to 3 days of sick leave without getting a MC.
36 % - It is a good way to ensure that the employee is really sick.
19 % - Some employees abuse the privilege to get many days of sick leave.
6 % - Some doctors issue MCs freely, even to employees who are not sick.
