If your establishment is covered by the Industrial Employment Standing Orders Act 1946, the model standing orders are binding on you until you establish your own certified standing orders.
Secondly, irrespective of the number of employees in an establishment, your hiring and firing are subject to those general principles stated by me, which are incorporated in specific Acts. For example, you cannot terminate a workman at will without paying him retrenchment compensation as laid down under the Industrial Disputes Act.
