Get all your questions about unemployment ready, including the forms filled in today... File asap! File as soon as they let you go.
If you have stock/equity decide now if your going to exercise it. You may have to pay taxes in addition to the exercise price.
Bring all your work stuff from home. Hand it over and get a receipt, nobody wants to play phone tag with a ex to get their stuff back.
If you have access to sensitive systems or passwords, put it in writing what you know and tell them they need to change those passwords now.
Make sure you keep contact with anyone you care about now, before you lose access to the systems.
Be the adult, let them you know these transitions are hard, compliment them for doing a difficult thing so well, make it clear there are no hard feelings. I've had multiple long term highly lucrative consultation arrangements after a layoff.
Honestly, the biggest yolo is to be professional, prepared, drama free. Don't even let it bother you.
I'm above this, I have my own plan, I have confidence... It will distinguish you.
I once had a new job lined up, but hadn't put my notice in, I got laid off before the Friday I was going to put my notice in. The firing officers complemented me on how well I was taking it.
Then 3 months later they hire me as a side contractor at 5x my salaried rate while I was still doing my new full time job.
So yeah... Yolo is about having your life together and being above other people's drama, a bit of luck helps too.
I'd count this as a YOLO. You only live once and choosing to live it with decorum and immaculate professionalism or playing the long game is also a valid response.
Maybe one day, they come crawling back to you? Take them for all they're worth or shove it back at them.
I had a lucrative job offer for a fairly senior role from a company that previously retrenched me. I got their senior management to wine and dine me. All in the guise of discussing the role, how I saw the future of the industry and my plan for taking the company to where they wanted to be in 2 years.
Then after all was said and done, I told them I wasn't interested. It felt good and besides I make way more now than they could have offered me and it would have taken me away from my family and put me in a very stressful role.
If you have access to sensitive systems or passwords, put it in writing what you know and tell them they need to change those passwords now.
I am in security, so I know the logical reasons for that even though someone is sure to say that is bullshit.
However, I left a job once and encrypted all critical passwords I knew on a USB drive and gave it to my manager. For the password, I created a riddle that only he would know. I gave my old manager (he was cool) the USB drive and walked. After about a week, he was laid off for pure money reasons. So a month goes by and I get a frantic phone call one morning asking for all the passwords to some super important systems and I was kind enough to know they had pointlessly fired the only person who would of had access. (They had blindly destroyed his remaining equipment and paperwork, so they were gone.)
It was intentional, encrypted and before enterprise password managers were common place. The key was a riddle and actual key was never actually written down anywhere. I sure as fuck didn't trust our network, so I couldn't store them somewhere accessible.
I am fairly sure the drive got put in our evidence safe which was then shredded with the other drives that were in there. (The company I was working for got bought by a venture capital group and nothing original was sacred.)
