Is it possible for me to change my availability while on the 90 day probation period? I began working at Target in late June (June 26) and I start college classes on September 1st. I work about 30 hours a week as a backroom team member. I want to work less hours when school starts, and at the moment I have open availability. I was going to ask someone about this but wanted to know if Target has let people change their availability for classes.
