 As Wyndham Mortimer, the UAW officer put in charge of organizing the campaign in Flint, recalled, when he visited Flint in 1936 he received a telephone call within a few minutes of checking into his hotel from an anonymous caller telling him to get back where he came from if he didn't "want to be carried out in a wooden box".GM also maintained an extensive network of spies throughout its plants.Mortimer concluded after talking to Flint autoworkers that the existing locals, which had only 122 members out of 45,000 autoworkers in Flint, were riddled with spies.
