Jack works as a mechanic in No Limits Inc., an automobile manufacturing company. While employed as a service technician for the defendant, Jack suffered back injuries in March 2005 and April 2005. Though he applied for leave, he did not undergo any medical treatment and did not provide an injury report in writing. Jack was absent through the month of June, calling in sick each day without providing any other information and not seeking medical treatment during this time. As Jack had exhausted his available sick leave and vacation leave, he was terminated when he returned to work on July 3, 2005. Can Jack sue his former employer for violating the Family and Medical Leave Act (FMLA) by failing to reinstate him in the company?
