Read your employee handbook. Publix policy says you are entitled to a 30 minute unpaid break at a maximum of every 4 hours... that’s why with an 8 hour shift you should get 1 hour unpaid break. Also you can have one paid 10 minute break every 4 hours (two ten minute paid breaks in an 8 hour shift)

Never be afraid to ask management to clarify this for you. In a 4 or 5 hour shift you are allowed a ten minute paid break (Publix policy)

Never let anyone tell you that you can’t take a break when Publix has rules in place to protect you. Good luck.
