A deadline grace period is the extended time the system allows for a reviewer to still attend to a workflow after they have missed their deadline. A grace period can be set by the Admin within the Admin > Workflow > Deadline settings. The grace period can be set to extend the deadline for a certain amount of hour(s) or day(s).
How an Admin can turn on grace period:
① Go to the [Admin] console on the left menu
② Click [Workflow] sub menu
③ For "Deadline" make sure it is turned on
④ Click the checkbox and enter the grace period time you would like for hours or days
⑤ Click [Save Changes]
Grace period will be enabled for deadlines. For example, for the grace period set above, if a reviewer's deadline is set to be at 1pm, the grace period will allow them to still make a workflow decision up until 4pm.
