Summer benefits enrollment ends July 28

If you haven’t reviewed your state insurance benefits, time is running out. The Employee Retirement System (ERS) will officially end summer enrollment on July 28. Therefore, you have this week to complete your summer enrollment changes. This also is a time to review your TWU Pioneer Extra benefits. During summer enrollment, you can enroll in new benefits programs or change your existing coverage. 

Note: If you don’t want to make any changes, you don’t need to do anything.
