Section 11 provides for the amendment of paragraph 1(a) of Schedule 3 to the principal Act by substituting "two weeks" for "one-half" and subparagraph (b) by inserting, after "product of", "two weeks of". These amendments are known as transitional arrangements which will allow for the payments of increased statutory redundancy levels as soon as the Act comes into force, following minor changes to the existing IT system. These arrangements will cease to have effect on the commencement of section 12. Section 12 provides for the amendment of schedule 3 to the principal Act by substituting new paragraphs for paragraphs 1, 2 and 3 to allow for enhanced redundancy payments of two weeks per year of service, plus one extra week's pay. Any "excess" days will be credited as a proportion of a year. These arrangements will come into force when a new IT system becomes fully operational.
