Medical Leave for Disabled Veterans Act This bill amends the Family and Medical Leave Act of 1993 (FMLA) to provide eligibility for specified medical/hospital care for an employee who: (1) has a Department of Veterans Affairs (VA) disability rating of between 30% and 50% and at least 833 hours of service with the employer (from whom leave is requested) during the previous eight-month period, or (2) has a VA disability rating of 60% or higher and at least 625 hours of service with such employer during the previous 6-month period. Medical/hospital leave shall also be provided to an employee who is not covered by the above provision but who retired from the Armed Forces by reason of a service-connected disability: (1) rated at between 30% and 50% at retirement and who has at least 833 hours of service with such employer during the previous eight-month period, or (2) rated at 60% or higher at retirement and who has at least 625 hours of service with such employer during the previous 6-month period. (Under current law, employees of an FMLA-covered employer become eligible for medical leave after 12 months on the job and at least 1,250 hours of service with such employer during the previous 12-month period.) A employee must submit a certification to the employer from the VA or the Department of Defense, as appropriate, to be eligible for such adjustment.
