SEBB replaces December 9 mailing with letter containing updated information

Below is a copy of an email sent to all OSD employees on December 19, 2019:
The School Employees Benefits Board (SEBB) December 9 mailing to Olympia School District employees contained incomplete or incorrect information and could be missing dependents due to a programming error. SEBB is mailing a corrected version to all 2,751 employees that were affected statewide.
The new letter will include updated dependent(s) and health plan enrollment information. This letter replaces the December 9 letter. Employees should review the corrected letter and, if necessary, submit any appeals based on the new letter.
If your letter is dated something other than December 9, and your letter has the correct information that relates to your SEBB account, then no further action is necessary.
