I have full insurance with target and I average about 22 hours a week. Im in school so I want to work even less than that. Do I have to work 20 hours a week to keep my insurance or can I work like 20 hours a month? In the summer I worked full time may-sept so I dont know how that factors also Ive worked for target more than 5 years so even though im part time i have full benefits. TIA!
