In terms of support, I found I was very supported by my coworkers as well as upper management. As for all jobs, upper management looks for you to be doing the right thing as well as going above and beyond for each and every guest as long as you do those things you will see benefits.
You should expect to receive a lot of support from the management team in Target. Every team has a team leader, you can go to this person with any questions you might have. The HR department is also very helpful. Don't be afraid to have questions, Target has an open door policy.
Being a part of the Flow Team is very much like a team sport with heavy emphasis on the individual players. The upper management will often assign individuals to work the same areas of the store consistently, so those individuals can become masters of those sections. Depending on how big the store is, the Flow Team may have one or two direct supervisors, and the store manager will be present often as well. These managers have to direct team members that may be scattered across the entire store, so you will never have a manager breathing down your neck, so to speak. I often felt like I made my own decisions as a Flow Team Member, and if anything came up I didn’t know how to handle or the proper protocol, the managers were always just a walkie-talkie call away. The stores often attempt to promote the team aspect by having a huddle at the beginning of the shift, and during the huddle, the managers often give encouragement to team members who have been doing well or who handled a problem exceptionally.
Support from upper management as a sales floor team member is good - for the most part, their leadership is accessible and they promote an open-door work environment. They will support you when the going gets hard, and will provide you with resources to succeed. Your relationship with your executive team lead (the supervisor of the team leads and senior team leads in your area of the store) is definitely something they prioritize. Team leads and ETLs get a lot of face-time with you when you are working, and are often working and completing tasks alongside you.
