I landed an unpaid internship a while back on a small news company but I quit after one month. I didn't include it on my resume because I didn't receive a verification letter, most likely because I quit all of a sudden.
I don't have a lot of work experience and I think including it on my resume would look better. I have gained a number of skills during that time, but I'm worried that any future employer would ask for a verification letter which I don't have, and won't ask for it.
Is it important for an employer to verify this? and is there another way to note this experience without having to provide this verification letter?
