I’m not sure you’ll be allowed to switch your preference. As I understand it there are district wide conferences calls happening today where SMs are informing higher ups about the preferences that were requested at their store and then being given direction on how to move forward.
But it’s going to be different at each location, there’s no harm in asking...
Some stores aren’t even able to offer or honor all three preferences, so you never know.

I am a three year partner who recently started development for ASM and I thought a lot about it and still ended up selecting preference 2. I think it’s a really great choice for partners, especially those with insurance through the company.

You might be able to. Call your SM ASAP. I did this morning and they said nothing was processed yet so I could change it.

I want to say it’s possible for you to still apply for partial unemployment if your not making enough money. You could still try that regardless. Unfortunately idk all the details for that.
