Held: Yes. The discharges constituted unfair labor practices regardless of
whether or not the employees were economic strikers or unfair labor practice
strikers. N.L.R.B. v. International Van Lines, 93 S.Ct. 74 (1972).
5. An employer refused to pay vacation benefits to employees who had been on
strike on a certain date.
Issue: Is this refusal an unfair labor practice?
Inc., 87 S.Ct. 1972 (1967).
Additional Matters for Discussion:
That a violation of the concerted activities provision does not have to involve a
union. It protects employees acting for mutual aid and protection.
That employer rules prohibiting solicitation during “working time” are
presumptively valid. Rules banning solicitation during “working hours” are
presumptively invalid.
That an employee’s preparation to testify under subpoena at trial of union activist
charged by employer with criminal wrongdoing constitutes concerted activity
which cannot be interfered with by the employer.
Interfering with Concerted Activities
Emphasize:
That the term concerted activity is given a liberal interpretation in order to
create a climate that encourages unionization, collective bargaining, and all
that may flow from such activity.
That the concerted-activity concept is quite extensive.
The right to engage in concerted activity has been expanded to cover the
actions of a sole employee under certain circumstances.
