Hi,
To be more clear, the following is about the weekly off under the law:
52. Weekly holidays. (1) No adult worker shall be required or allowed to work in a factory on the first day of the week (hereinafter referred to as the said day), unless:
(a) he has or will have a holiday for a whole day on one of the three days immediately before or after the said day, and
(b) the manager of the factory has, before the said day or the substituted day under clause (a), whichever is earlier:
(i) delivered a notice at the office of the Inspector of his intention to require the worker to work on the said day and of the day which is to be substituted, and
(ii) displayed a notice to that effect in the factory: Provided that no substitution shall be made which will result in any worker working for more than ten days consecutively without a holiday for a whole day.
Weekly off cannot be given to individuals based on whatever is given in form 11, it has to be followed. If you want to change the weekly off to another day, amend a new form 11 and get it done.
