Full-time Nurses - Vacation Planning

[coffeetea]

I'm a full-time new grad RN working in BC, Canada and I was looking to get married in 2025, and book venues. For those who work full-time, how far in advance do you get your schedules? I'm worried that the schedules might come out too late and most of the things will be already booked by others for my wedding. Is it okay to go ahead and book dates, and then request time off for marriage? Are employers generally understanding?  I'm worried it might not be approved.

This is a question for your manager. I don't see how it would be a problem, unless your time off includes a major holiday.
