In a strike procedure plan, what should security personnel be briefed by company management about?

In a strike procedure plan, it is essential for security personnel to be thoroughly briefed by company management on several crucial aspects, including company policy regarding the strike, property lines, and the importance of documenting any illegal activities.

Understanding the company's policy regarding the strike equips security personnel with the context needed to enforce company rules and respond appropriately to various situations that may arise during the strike. This knowledge helps them maintain order and protect the interests of the organization while adhering to legal guidelines.

Familiarity with property lines is critical in a strike situation. Security personnel need to know the permissible areas for each party involved, ensuring they can effectively manage access and restrict individuals from entering areas they are not allowed to, thus preventing potential conflicts or trespass.

Taking detailed notes of any illegal activities during a strike is vital for potential legal action or resolution after the event. Documentation can serve as evidence if required and can help in understanding the dynamics of the situation.

Thus, a comprehensive briefing on all these topics equips security personnel to perform their roles effectively, demonstrating how each component is essential for the safety and security of everyone involved. This comprehensive approach is why the choice indicating 'all of the above' is the correct answer.
