They are required by ADA law to have an interactive process. If they choose not to, you file a claim with the DOL, but I suggest you make very very sure that you follow all of the employer's call in procedures when needing time-off under either law. After filling out ADA and/or FMLA paperwork, you should not be required to bring a dr's note for each occurrence but the employer can ask you to recertify every 6 months unless there is a change (such as needing more than originally stated).
