Company policies and procedures are in place to protect the rights of workers as well as the business interests of employers.
Depending on the needs of the organization, various policies and procedures establish rules regarding employee conduct, attendance, dress code, privacy and other areas related to the terms and conditions of employment.
Employee Conduct An employee conduct policy establishes the duties and responsibilities each employee must adhere to as a condition of employment. Conduct policies are in place as a guideline for appropriate employee behavior, and they outline things such as proper dress code, workplace safety procedures, harassment policies and policies regarding computer and Internet usage.
Such policies also outline the procedures employers may utilize to discipline inappropriate behavior, including warnings or employee termination. Equal Opportunity Equal opportunity laws are rules that promote fair treatment in the workplace. Most organizations implement equal opportunity policies -- anti-discrimination and affirmative action policies, for example -- to encourage unprejudiced behavior within the workplace.
These policies discourage inappropriate behavior from employees, supervisors and independent contractors in regard to the race, gender, sexual orientation or religious and cultural beliefs of another person within the organization.
Attendance and Time Off Attendance policies set rules and guidelines surrounding employee adherence to work schedules.
Attendance policies define how employees may schedule time off or notify superiors of an absence or late arrival. This policy also sets forth the consequences for failing to adhere to a schedule. For example, employers may allow only a certain number of absences within a specified time frame.
The attendance policy discusses the disciplinary action employees face if they miss more days than the company allows.
