Final answer:
The statement is false; alcohol-related workplace accidents can involve non-alcoholics, and various factors contribute to these accidents besides chronic alcoholism.
Step-by-step explanation:
The statement that the problem of alcohol-related accidents in the workplace is caused almost entirely by hard-core alcoholics is false. While chronic alcoholics may contribute to such incidents, alcohol-related accidents can also involve individuals who are not addicted to alcohol.
Factors like a history of aggression, perceptions of unfair treatment, and job security can influence the likelihood of workplace violence related to alcohol. Additionally, alcohol's effect on coordination, judgement, and behavior must be taken into account, as even social drinkers can have these impairments after consuming alcohol, which can lead to accidents or aggression in the workplace.
