A number of studies show that building a happy

a good and safe investment. A number of studies show that building a happy company will
generate high profits. Cherniack's research shows that investing in health safety is a safe profit.
Therefore, the study of Sun Coast's ROI needs to find similarities with previous studies.
Research Objectives
The purpose of this paper is to help Sun Coast study the company's issues and then devise
appropriate strategies to improve the working environment as well as to create the company's
expected profits. The current core issues of Sun Coast lie in the working environment of the
company. They need to analyze employee health issues, employee policies, return on investment
through data on Particulate Matter, Training Program, lead level, Sound - Exposure. These are
the main variables that are closely related. The analysis of these variables will help Sun Coast to
have methods to improve the company's activities in the near future.
