Going on vacation

I have a new job. And I’ve had 2 vacations booked before I started my job. One in September and one in October. I told my manager in my interview.

I requested one week off in September and then one week off in October.

I feel like my manager forgot about it and when he sees it to accept my request, I think he’s not gonna be happy. And I think my co workers are gonna be mad because they are going to have to do my work while I’m not there.
