Unpaid Wages / Overtime in restaurant - What Are My Options?

Quick background on my situation — any input appreciated.

gig company reclassifying workers. I've been dealing with this for about 4 weeks now and the situation isn't improving.

I have worked at this company for 10 years. My position is non-exempt and I do not have a written employment agreement beyond the standard offer letter.

Has anyone been through something similar? What worked for you?

Following this thread — bump -- also need to know this

I've dealt with this before.

In my case idk, it took about 3-6 months to resolve. The key was having everything documented.
