This is actually 3 different positions in my store. All are part time and EARLY mornings. All floor work MUST be done before store opening. So those early sale days mean even earlier work shifts. (Some as early as 4am.)
The signing team usually works 6am to 10am but hours will vary depending on when the sales go up or come down. (Usually up on Wed/Thurs and down on Sun/Mon) They average 12-20 hours a week.
The pricing team (markdowns) usually works 6am to 10am. The first and last Sunday of the month are usually the biggest markdowns but they work according to the markdown calendar. They average 12-20 hours a week.
The merchandising team usually works 6am to 10am. They work whenever we get a truck. Usually they have 3 days notice of when the truck is coming. This position is one of the worst as far as scheduling goes. If they cancel a truck, or it doesn't fill fast enough, your days will be switched on you. Many times you won't know if your working until 5pm the night BEFORE! Weekly averages would depend on the size of your store and how many trucks they get in a week.
If you are looking for something for after you put your son on the school bus, this isn't it. An 8-2 job just doesn't exist at Macy's, which is unfortunate. Some of our best employees have been SAHM's that just wanted a little "something". Sadly, Macy's doesn't work that way anymore. I've been with them for 19 years and the last 2 have been the worst.
If you have any more questions, PM me.
