On 15 May 2024, the role of the Prime Minister of Singapore was passed on from Mr Lee Hsien Loong to Mr Lawrence Wong. A book of tribute was produced for the outgoing Prime Minister to honor his services and contributions towards the Labour Movement.

The tribute book concept was about penning down a thank you note to him. The book documented the memories between him and the labour movement, from his unwavering support for Tripartism, to his heartfelt compassion for the workers of Singapore.
