Who do I ask for a reference after a layoff? - first time posting

My manager was laid off too and I am unsure who to use as a reference. A colleague offered to vouch for me. Who did you use?

Use a professional network to find a former manager. Many will still write a note.

Thanks for writing this out. I went through something close to it 6 months ago, and it got easier once I kept a simple log of every call and form.
