When users create a request child to a task they are working on, I want them to be able to designate that request as either blocking the parent task (from any further progress) or not blocking the parent task (requests can be worked simutaneous with the task).
This way, a user can properly report and see in the "to-do" list of available work tasks that are completely available to work as opposed to those that are otherwise available but blocked by an open request. This clarifies accountability when a user has many tasks to sort through (separating the ones they need to do vs the ones they can't) and helps as a manager to see who is really responsible for a task that is held up on a project.
