Sure. 'Upton Sinclair's 'The Jungle' is a great example. It exposes the harsh working conditions in the meat - packing industry, very much in line with the themes of labour. Then there's 'North and South' by Elizabeth Gaskell, which looks at the differences between the industrial north and the rural south, with a focus on the working classes in the north. Also, 'A Tale of Two Cities' by Charles Dickens has elements related to the labour of the common people during the French Revolution.
One could be 'The Grapes of Wrath' by John Steinbeck. It shows the struggles of migrant workers during the Great Depression, which is related to the broader concept of labour. Another might be 'Hard Times' by Charles Dickens, which delves into the lives of industrial workers. 'Sinclair Lewis' 'Babbitt' also gives insights into the working life and the disillusionment of a businessman, which can be seen as a form of labour - related exploration.
Some 'labour day novels' that come to mind are 'Germinal' by Emile Zola. It portrays the lives of coal miners and their difficult working conditions and struggles. 'Howards End' by E. M. Forster also touches on the social and economic differences related to labour and class. Additionally, 'The Mill on the Floss' by George Eliot, while more of a family - centered story, also shows the importance of work and labour in the context of a rural community.
