Getting references after a company closes - first time posting

My manager was laid off too and I am unsure who to use as a reference. This is my first time dealing with any of this. A colleague offered to vouch for me.

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.

Ask former colleagues and supervisors in a short message and give them a summary of the job you are applying for.
