Answer:

d

Explanation:

The one action listed in the question that would suggest unfair labor practices would be if Hyper-Tech managers prohibited the distribution of union literature in the company cafeteria. This is because a company can prevent employees from partaking in other tasks and getting distracted while on duty. When an employee is on duty they are getting paid to focus and complete their responsibilities. An employer also has the right to prevent non-employee individuals from entering private property such as their facility. What a company cannot do is prevent their employees from deciding what the literature that they want to read or the decisions that they want to make outside of work hours. Therefore, preventing the employees from accepting literature while on their break time would be considered unfair labor practice.
