Family Dollar have a dedicated page setup to help employees access their W2 form.
They call it the "Doculivery Team Member self-service system" .
Pay stubs are available going back as far as 2009.
And online W2 forms are available for the past 7 years.
They also list these important contact details should you need more help:
"Current or former Team Members with questions may Ask HR by visiting www.MyFamilyDollarLife.com , or calling the HR Contact Center at 1-866-377-6420, Monday through Friday, 8 a.m. To 8 p.m. Eastern."
If you're still struggling to get your W2 form from Family Dollar, then head back on here and get in touch - and I will see if there are any second steps you can take.
Good luck!
