The practice of commemorating years of service at a single employer emerged in the early twentieth century alongside the growth of large corporations. Companies like IBM, General Electric, and AT&T formalized recognition programs that awarded employees pins, plaques, and certificates at milestones of five, ten, twenty, and twenty-five years.1 The ceremonies reinforced organizational loyalty during an era when lifetime employment at one company was both common and expected.

Service award programs expanded significantly after World War II, when employee retention became a competitive concern for large employers. By the 1950s, the gold watch at retirement had become a cultural symbol of a career spent entirely at one organization.2 The message was clear: longevity was the highest form of professional commitment, and the employer reciprocated with visible tokens of appreciation.

When LinkedIn introduced automated "work anniversary" notifications in the 2010s, the platform applied the logic of service recognition to a labor market where the median employee tenure was 4.1 years, according to the U.S. Bureau of Labor Statistics in 2020.3 Contacts received prompts to congratulate colleagues on anniversaries at companies those colleagues might already be planning to leave.

The shift from a gold watch at twenty-five years to a digital notification at one year mirrors a broader compression of the employment relationship. Gallup reported in 2022 that roughly half of American workers were actively watching for or seeking a new job.4 The ritual designed to celebrate permanence now marks a duration that an increasing number of workers regard as temporary.
