Explain the need for training and development for this company and describe the purpose and the training program objectives effectively?

As a newly appointed director of training and development for a mid-size construction company, Alliah Construction, a project requires my immediate attention. One service provided by my company is residential roofing installation, repair, and replacement. Each job is performed by a crew consisting of an on-site supervisor and laborers with varied skill levels. Some members of the crew have limited English-speaking skills. Although management knows that construction work is inherently dangerous, the company has experienced three serious accidents on roofing jobs in the past month. An accident report from an OSHA inspector identified numerous safety violations that could have contributed to the accidents.

Can you help me explain the need for training and development for this company and describe the purpose and the training program objectives effectively?
