age you have to be to work at wendy's
Report Abuse. 1  14. Source(s): My brother. 2  not 13.... 3  Probably not 13, but you might be able to be 14.  16 and 1  up. The legal age for working is 14 I believe (it may depend on where you live).  No I think you have to be 18 or older or maybe 16 you should visit their website or call them. I started at Wendy's when I was 15 and I was the youngest person at our local store. If I were you I would just call and ask or go in and talk to the manager.
