2 kinds of workers paid by results

Workers paid by results may be classified into: [1] Supervised workers; and [2] Unsupervised workers.

As can be inferred from the term itself, "supervised workers" are those whose manner of work is under the control of the employer. On the other hand, unsupervised workers are those whose work is controlled more in the results rather than in the manner or method of performing the work.
The law does not distinguish among workers paid by results. Therefore, the workers may be on pakyao (alternatively spelled “pakyaw”) basis, takay basis, or piece-rate or output basis. All of these results-based workers are similar in character in that they are all paid on the basis of the results of their work. When the law does not distinguish, we should not distinguish.
