Who do I ask for a reference after a layoff? - 6 months and counting

My manager was laid off too and I am unsure who to use as a reference. I would rather hear the honest version than the polite one. HR only confirms titles and dates.

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

A client reference worked well for me. It shows you deliver outside the company too.
