香港教會將每年最接近五月一日國際勞動節的主日定為「勞工主日」，特別關注香港勞工處境。2021年勞工主日，香港基督教工業委員會即以以賽亞書所敘述的安息日傳統來反省精神健康與勞工保障之關係。
此外，香港基督教工業委員會與香港天主教勞工事務委員會亦以「確立失業保障、落實生活工資、將新冠肺炎納入職業病保障」為題，發表勞動節聯合聲明與禱文，呼籲香港教會與社會各界人士共同改善勞工權益，並為勞工多方禱告。
求上主開啟我們的心靈，多加關注工人處境；又燃起我們的愛火，身體力行為勞工階層提供援助；又藉我們的工作參與上主的創造工程，使每個人的勞動尊嚴更趨完善，獲得滿全生命。
以下是2021年勞工主日的完整講章及禱文：
The Hong Kong Church has designated the Sunday closest to the International Labour Day on May 1 as the "Labour Sunday", with special attention to the labour situation in Hong Kong. On Labour Sunday 2021, the Hong Kong Christian Industrial Committee prepared a theological reflection on Holistic Well-being with Sabbath tradition in Isaiah 58.
In addition, the Hong Kong Christian Industrial Committee and the Hong Kong Catholic Commission for Labour Affairs also issued a Labour Day Joint Statement and Ecumenical Prayer with the theme "Ensure the Unemployment Protection, Enforce the Living Wage, and List the COVID-19 as an Occupational Disease." We urge the Hong Kong public and the Church to improve the labour rights and pray for the challenging labour situation in Hong Kong.
We pray for the Lord to open our eyes and ignite our fire of compassion that we can offer support to the labours in need and to uphold the labours’ dignity and fullness of life through our works.
