If you were awarded a reserve line this month then this is how it works.
The first thing to do is decide where exactly you want your vacation. Go to VIPS, Bid Period Processing, and Vacation Adjustments for all of the options. On an R line, you can slide up to 5 days in either direction and extend it usually a maximum of 3 days in either direction. You will be paid the R day value for each day of vacation regardless of what days it actually hits. So if you have 7 days of vacation this month, you will be paid 7 x 4:35 or 32:05 hours for that vacation block. Since February is a 4 week bid month, there are 15 R days total so you will owe 8 additional R days. If you decide to expand your vacation to say 10 days, then you will be paid 10 x 4:35 or 45:50 hours for your vacation block and will owe 5 additional R days.
Next go to the VIPS link, then Bid Period Processing, then Reserve Line Reconstruction. This is where you will put in your request on where you would like any R days either removed or added so that you have the remaining R days you owe on your schedule. These R days cannot be placed on your vacation footprint or in the 48 hour buffer on either side unless you waive that on the Vacation adjustment section.
You can always hit the link Bid Period Processing Summary at the bottom of the page to show all your requests that will be processed during the Conflict/ Input window.
Just get it in before 0700 on Monday or you will get what you get! Good luck !
