Noting that the test for violations of sec. 8, now codified as sec. 8, of the NLRA is whether "the employer engaged in conduct which, it may reasonably be said, tends to interfere with the free exercise of employee rights under the Act," and that actual or successful coercion need not be shown in order for the Board to find a violation
In N.L.R.B. v. Syracuse Color Press, Inc., 2 Cir., 209 F.2d 596, we have upheld the Board in finding coercion in the pointed cross-examination of five employees as to union organizing activities within the plant.
