Reviews are always some point in april. Last year I got my review towards the end of april. They rate based on your performance. If your cashier: do you get red cards? Or try to ask every guest if they would like to save 5%? Do you double bag heavy items? Do you have good attitude with guests?
Do you talk about cartwheel app to guests?
If you work on sales floor: do you finish tasks on time & if not do you use sense of urgency? Helping guests all the time is a key to a good review. Going up for backup cashier and being first to answer calls is very good. Also good sportsmanship.
You can only get up to a 5% higher pay rate than you already have.
