Which of the following is a disadvantage of on-the-job training?

• A. It is safe for the trainee
• B. Output may be lost due to mistakes by the trainee
• C. It requires no supervision
• D. It guarantees immediate quality

Answer: (B)

On-the-job training means learning while doing real tasks in the actual work environment. The main downside is that the trainee will make mistakes as they pick up skills, and those mistakes can slow production or lead to imperfect output, so output may be lost. This reflects the reality that learning by doing in a live workflow can disrupt efficiency and quality until the trainee becomes more competent.

The other statements aren’t reliable disadvantages: training isn’t guaranteed to be risk-free or require no supervision, and it certainly doesn’t guarantee immediate high quality—the learner needs time to build skill and accuracy.
