Respond to Job Separations

When an employee is separated from employment and files a claim to collect unemployment benefits, any employer listed on the claim is notified via letter and are required to submit job-separation documentation. This documentation allows us to make decisions about allowing or denying unemployment benefits to be paid to the previous employee.

Employers can respond in two different ways:

Request for Facts About a Former Employee's Employment, Form UIB-290


Online through SIDES E-Response

Both large/multi-state and small employers are encouraged to sign up to receive and respond to job-separation notifications online using a tool called the State Information Data Exchange System (SIDES).

Employers participating will be able to:

  • Respond to Request for Facts About a Former Employee's Employment, Form UIB-290, in an easy and efficient online format.
  • Receive a date stamped confirmation, avoiding time and cost of unnecessary hearings.
  • Attach additional documentation to job-separation responses.
  • Eliminate delays related to mail delivery.
  • Provide speedy and efficient resolution of separation and related issues.
  • Keep premium rates and business costs low due to reduction of state- and employer-related administrative costs and by reducing improper payments through streamlined fact-finding processes.

If you are utilizing a third party administrator or professional employer organization for your payroll and unemployment premiums, you do not need to sign up.
