User's assigned to a task has full access to modify the status of their task, EXCEPT in their "my work" area. On the task as it appears in their "my work" area, they are NOT presented with the status button next to the "how's it's going" button. It will be so much more efficient to allow them to change their status here and to not make them go into the actual project to change their status. If a user has permission to change the status of their task, they should be allowed to have permission to change the status of that task, no matter what screen/view/area they are in, in Workfront.
