By law every business must have posted, an equal employment opportunity poster size board regarding sexual harassment, race, color, religion, sex, national origin, disabilities do's and don'ts, that way if an employee has an issue with anything, it is posted so all can see.
*Having weekly or monthly meetings with employees is a good way to communicate, to see if there are any problems with people, job descriptions etc.
*Communicate with each of my employees.
*Give my employees little incentives to let them know that they are appreciated.
*Treat everyone like I would want to be treated.
If an employee is not happy at their job, then the work place will be affected, but if they are happy and feel appreciated, your business will run smoothly.
