I would not have language in the employee contract about termination of an employee's services after a certain number of sick days. The reason is that the employee could suffer a work related injury and you would not be able to terminate the employee legally due to this.I would have language in the employee contract referencing any employer-employee handbook and expected conduct. Your contract should state that the employee is terminable at will. I recommend that you consult with a labor attorney for the wording to be drafted in any employee contract to protect your interests and have the attorney draft the agreement that you want done.
