2nd of 3 Times – Military Troops Deployed to Dayton
II. The 1948 Univis Lens Co. Strike – Nearly 80 years ago
DPD faced a succession of dangerous labor strikes over the next decades (e.g. Dayton Steel Foundry), but 1948’s unrest is remembered as the worst. The labor movement was progressing as many war veterans entered the workplace at industrial plants. The “Red Scare” was in its early years – prompted by disturbing news reports about Joseph Stalin, the Soviet Union, and the Cold War – and the labor movement was pegged by politicians and press as being under communist influence.
The Univis Lens Company had produced various kinds of lenses for the U.S. military during WWII. It was located at 401 Leo Street, just west of North Keowee Street. The building complex was on the north side of the street across from where McCook Avenue curves into it. This was an industrial area. Land further west to the Great Miami River was undeveloped, unlike today. The CIO’s United Electrical Workers, Local 768, asked management for a raise of 10¢ per hour but the company wanted to extend negotiations for 60 more days.
UE Local 768 refused management’s request. When 600 production workers walked off the job at the Univis Lens Company on May 5, 1948, a labor strike began. It was not long thereafter that a picket line formed outside the plant. By June 2, the talks had brought about ill-fated discord. The workers and company had reached a total impasse that would draw in Dayton patrolmen. The picketing was relatively peaceful... at first.
A company “back-to-work movement” was interrupted by the picketers. Tensions at the strike line were aggitated and stirred by their fiery union leader, Louis Kaplan. A small security squad (top left) approached the picket line led by Sgt. Richard Grundish (chevron on sleeves). It was the job of the police to ensure that both the members of UE Union Local 768 on the line and management personnel remained in peaceful coexistence as they dealt with their differences.
