The first guestion I have is, how long have you been with Target? If you just started then you will not be eligible yet. The second question is, how many hours are you working each week? If you are full-time (defined by Target as 32+) hours, you will be eligible for full-time benefits. If you are part-time you can get some part-time benefits.
Basic Rules:
ETLs: Eligible for benefits from day one.
Tms: 6 months to become eligible. 32+ hours per week avg for full-time. 21+ hours per week for part-time.
Hope this helps.
