My doctor signed me to a 4 day work week. Can my employer refuse this?
Can they also make the doctor fill out a detailed medical assessment. For them to determine if they can accommodate me.

Thank you for your question. Your employer has a duty to accommodate you up to the point of undue hardship. If the doctor's letter that you provided to your employer to request the accommodation of a 4-day work week is unclear or ambiguous, the employer can request further information about your abilities (usually through the completion of a Functional Abilities Form). If your employer refuses to accommodate you after receiving this from your doctor, you should contact us at the number below to discuss your options.
