12/19 conversation with Philip Carr, CMS Manager:<br /><br />PC: A unit block is 1 week vacation - 7 days. If an extra board person with Wednesdays off bids a unit, you can give Wednesday off for a single day to someone else.<br /><br />PC: If someone bids an entire week by specifying a unit you can&#039;t give that week to anyone else but you may be able to give open single days within that week.<br /><br />PC: If someone has that (Unit) week they have it. They can&#039;t lose it unless they bid out of the crew base.<br /><br /><br />With that being said, this note will appear on the calendar: &#039;Green patterned cell indicates &#039;pending available&#039; single days within an awarded unit week. Requests for these dates will be accepted but all awards will be held pending the outcome of any Optional Displacements if the date requested is after one or more optional effective dates. If there are no Optional Displacements between the date the request is made and the vacation date requested, it will be awarded.&#039; <br /><br />This will protect the week for the person who was originally awarded the unit in the event they either get bumped, or bid another job within the crew base (on an Optional) with different days off. They will have first priority, but a person who gets bumped or bids another job will still have to submit a date change request via email to secure the new days they need off, it is not an automatic process.<br /><br />Last optional displacement EFFECTIVE dates were May 15, 2017 and November 20, 2017.
