Change your 401k automatic payroll deduction to 0 ASAP!
If you got laid off, cash is king, don't worry about retirement at this moment - changing to 0 will increase your paychecks for the non-working notice period. If you think you might be laid off or know you are going to be in next round, keep this tip in mind. FYI - if you lose access, you can still get this info via Total Comp Online.
Benefits - Make all medical, dental, eye doctor appointments and refill all prescriptions ASAP. I called my doctor to tell them I was laid off and they called in extra refills for me. Anything you have been putting off, get done now. I had a couple procedures I'd been postponing due to work.
If you have the Vision insurance, it starts fresh every January - it does not matter if you got new glasses in December. I got new sunglasses I desperately needed and my kid got a new pair of regular glasses.
There are a lot of emotions that come with this, so stay strong and I believe we will all end up better off from this down the road. Peace.
