Yes…kind of. (If you haven’t been to johnfbell.com and used his reserve calculator, I highly recommend it…it will tell you how many on call days you’d have/X days you’d have). Vacation prorates the number of on call days you’ll have.

Unless your seniority won’t allow it, there are multiple ways to do this.

You could bid a line with the days off you need then else start next if you don’t get it.

You could bid reserve and put all your on call days at the start of the month and place all your x days at the end.

The obvious way would be to put your vacation on the week you need. (Keep in mind starting next vacation year the new PWA guarantees you off 48 hours prior to the start of your primary vacation)

If you can’t get the exact week you need, you could bid vacation on a different week in May and slide your vacation when you bid in April.

If you couldn’t get any weeks in May, you could place it later in the year and try vacation move up (processed a month in advance…see the SRH)

Finally, you could yellow slip as much as you could in the beginning of the month to ensure you’re “full” by the days off you need.

There are other ways as well (IVDs, PD, APD, etc) but these should give you a good idea on how to do it.
