Answer:
A) The picnic amounts to a captive audience meeting held within 24 hours of the election.
Step-by-step explanation:
This is a violation of the NLRA since the company should not intervene with the desire of their workers to join or not a union. The fact that the employer is using a company event to try to convince his employees would be a flagrant violation of the NLRA since the employees are required to be there and listen to him without being notified that the picnic was going to be used for that purpose.
