When to Make Changes

To get many of Lam’s great benefits, you must enroll online. After you’ve enrolled, you’ll also manage changes to your benefits online when you experience a qualifying life event, such as marriage, birth or adoption of a child, or loss of other benefits coverage.

Each fall, during annual enrollment, you can choose new benefits and make changes to your current benefits, even if you haven’t had a qualifying life event.

Be sure to complete your enrollment by the applicable deadline:

  You must enroll by
New employees 30 days from your date of hire
Qualifying life event 30 days from your life event
Birth of a child 60 days from the child's birth
Annual enrollment The Open Enrollment period deadline (in 2020: November 15)

If you have any problems logging in, email the Benefits Help Desk or call 877-291-9494.
