I think there is an average hours per week component as well.
This is based on an old post:
You may be eligible for the Target retiree discount privilege, as well as a retirement gift, if you meet all of the following criteria:❏❏ Are at least 55 years old when you leave the company.
❏❏ Have 10 years of credited and continuous service, starting after your latest hire date. A year
of credited service is a calendar year in which you were paid for 1,000 or more hours.
Team Member Discount
Your active team member discount ends on your termination date.
If, as of this date, you were at least age 55, and (1) have 10 years or more of continuous and credited (1,000 or more hours per calendar year) service, or (2) were an active team member on December 31, 2002 and have five years of continuous and credited (1,000 or more hours per calendar year) service, you and your eligible dependents are eligible for the retiree discount.
