Work queues can suffer from poor performance under certain circumstances. For example, they do not scale very well due to contention, as each request from the queue must be handled atomically. Also, if the tasks are very small (e.g. arithmetic operations), the overhead from constantly querying the work queue could exceed the performance gains from doing the dynamic assignment.
