When a request for separation information is posted to the SIDES E-Response website, an email notification, which includes the employer’s PIN, will be sent to the employer.

Each request has a Response Status and a Due Date. The employer will be able to tell which responses have already been submitted and which requests are new. To provide the requested separation information, the employer clicks on Create Response, enters the requested information and submits the response.

22. How can I submit attachments to the separation information?
Near the end of the process for entering an E-Response, the user will arrive at a screen that provides step-by-step instructions for including an attachment(s) with the E-Response.

However, the total size of all attachments to a single response is limited to a maximum of 5 MB.
23. How can I modify my response?
After a response has been submitted, it remains on the SIDES E-Response website for 30 days from the date of the
request. If, within that 30-day period, there is a need to correct, or provide additional information, the user can log back onto the E-Response website, identify the claimant on the Requests page and click Create Amendment. The same series of screens will be presented. Before submitting an amended response, the user will be asked to explain why the previous response is being amended and what has changed. After the amended response is submitted, the user will be able to see both the original and the amended response. An E-Response can be amended up to nine times.
