The department may require comprehensive medical or psychological examinations to reevaluate your continued eligibility for disability benefits. For catastrophic benefits the department may also require or offer to provide comprehensive vocational examinations and/or submission of earnings information to evaluate your continued eligibility. You are required to contact the department if your medical/vocational or financial situation changes.
If you believe you are capable of returning from your disability to work for your former employer and your employer agrees that you have met their requirements (examples could include a fit for duty test or polygraph), your disability benefit will end on the date you start working, as reported to the department by your employer. If you do not meet the requirements of your employer, you may challenge your employer's decision through the collective bargaining process, or other legal process against your employer.
