Below you find the article as published in the current CWA. Further below we provide some comments and explanations for this article.
Like always it is the obligation of the company to follow these rules and a pilot is entitled to a roster reflecting these rules. If a pilot notices a non-compliance with the CWA it is his/her right that his roster will be changed to be fully compliant with the CWA.

36.10.3 Rest at home base on Eastward-Westward or Westward-Eastward transitions (EWWET) In case of an Eastward-Westward or Westward-Eastward transition at Home Base, at least 3 Local Nights of rest at Home Base are provided between alternating Rotations.

This article states that when a pilot is transiting through Home Base from East to West or West to East, a minimum of 3 local nights of rest must be provided.
EWWET is defined in Part III of the CWA as “Eastward-Westward and Westward-Eastward transition means the transition at Home Base between a Rotation crossing 4 or more time zones in one direction and a Rotation crossing 4 or more time zones in the opposite direction”
Please note, the intention of the rest at Home Base is to have a pilot acclimatised at Home Base in order that he/she is rested for the next duty or series of duties.
If pilots feel that they are not acclimatised at the Home Base before the next duties then they should extend their rest time and complete a proactive fatigue report.
Example (EWWET)
A pilot operates a rotation all the way to HKG and back to LUX. In this rotation, he crosses 6 time zones to the East [LUX (UTC+2)/HKG (UTC+8)]. Due to the nature of his trip he would only need a Minimum Rest Period for time zone compensation according to 36.10.2 of 2 local nights. However, his next Duty is a flight from LUX (UTC+2) to JFK (UTC-4). Because he already crossed more than 4 time zones on his last rotation and is scheduled to cross again 6 time zones to the West, the Minimum Rest Period is 3 local nights according to 36.10.3.
