In addition to being able to give up shifts, you can also pick up available shifts using the TimeForge Employee mobile app. Keep in mind that you are not responsible for a shift until your manager has approved the pick-up.
Select Pick Up Shifts from the side menu
Find a date with a shift you like and tap the Pick Up button
You can also use these steps to pick up one of your own shifts that you've given up by accident.
Click OK to confirm pick up
Click OK to acknowledge warning
This warning is simply a reminder that you are not responsible for the shift until a manager has approved the change.
