To bid for an Open Shift, you will need to be on the Open Shift Bid Tab found at the top of the page.
Click on a Shift link that appears on the Open Shift Bid calendar and the details of the available shifts are listed.
Select which Open Shift you want to bid for and click on the blue text link "Bid" that is on the right-hand side of the listing.
Once you click on the "Bid" link, you will be taken to a confirmation page, where you will need to click either the blue button marked "Accept" or "Cancel". Be certain that you want to bid on the shift, because if you are awarded the shift from your Supervisor, you will be obligated to work the shift.
Once you have selected to Accept your bid, RosterApps notes your bid, and that is the end of it, unless you are awarded the shift by your Supervisor, and in that event, you will be notified via e-mail. If you are awarded the shift, your Calendar will show the new shift in an Orange color, letting you know that it is from a Claimed/Assigned Open Shift.
