Workplace Safety

A workplace can be referred to as a space where people work together for the accomplishment of a common goal of the organization. Here, people can be a worker, an employee, and an employer. A person can be said to be an employer if he/she gets the job of organizational goal accomplishment through other persons, and that person gets paid for his/her service. All employees can also be referred to as workers. An employer may also hire workers of other categories which require specialized skills to finish a work. Both employees and workers along with the employer form the primary occupants of a workplace.
