An employer of a unionized plant was facing economic difficulties and employee discontent. It established five employee committees to suggest company policy on absenteeism, smoking, pay progression and attendance bonus programs. The committees consisted of 6 employees and one or two managers. The employer selected the members of each committee. The committees met on company property on paid company time. Any proposal was submitted to the employer for approval before being implemented. The union objected to these activities. Are these mandatory topics and has the employer committed an unfair labor practice? Explain.
