This month, we discuss examine Lupton’s famous study of worker-management relations, On the Shop Floor: Two Studies of Workshop Organization and Output published in 1963. Tom Lupton spent 12 months as a factor worker in two different settings examining why workers intentionally worked at a level below management expectations. He found that social structures formed that protected workers from overuse or abuse by management and ensured a stable pay. These structures discouraged workers from working too hard or not hard enough. In Part 1, we will examine the cases in depth and present Lupton’s findings.
