Who do I ask for a reference after a layoff?, retail manager here

The company closed and I am not sure how to reach former colleagues. This is my first time dealing with any of this. A colleague offered to vouch for me. Who did you use?

I kept a note of my results so my references could be specific. They appreciated it.

Thanks for writing this out. I went through something close to it 9 months ago, and it got easier once I kept a simple log of every call and form.
