Who has worked the longest at one job?

The record for the longest tenure at one job is often attributed to Walter Orthmann, who worked for 84 years at a textile company in Brazil before retiring in 2021. However, there are other notable long-term employees, such as a few individuals who have worked over 70 years for various organizations. The specifics can vary by criteria and the type of work, but Orthmann is frequently cited in discussions about long-term employment.
