Strictly speaking, if you're in your first 90 days you shouldn't be allowed to get any time off unless it's a doctor's appointment or emergency. However, like most things at Target, what should happen and what actually happens are very different. My STL doesn't care if a time off request came from a new hire. I have to give it to them as long as they submitted it on time. This means all of these new hires who suddenly want 1 week in July off + another 10 days in August, get their time off. Doesn't matter that they were specifically hired to work those days. However, when they re-apply in November or next summer, I sure as hell won't be re-hiring them.
So many people like to complain that Target is terrible, yet they'll re-apply because they need the money. So just think about how your vacation will look from a business perspective.
