How to allow permissions for technicians for tasks at Change or Problem level

For a user definied as technician, I detect that permissions to view tasks into Problems or Changes isn't allowed. Apparently, I don't retrieve differences with definitions into Service Desk for that user and the other Technicians whose tasks are allowed.
