I just started driving and the sups asking me to help other drivers... I've been helping out other drivers...last week one driver I helped gave me 70 packages when it was already 5pm when I meet up with him. I don't mind helping out at all but damnnn...today I just got done with 180 stop and its 6:30 pm. the sup called me and wanted to me help out a driver. Its dark out and I'm tired. What advice can you guys give me?
