Have you ever worked with someone who had a bad attitude? If so, then you know that a co­worker's constant arguing, complaining, gossiping or backbiting can ruin company morale and devastate job performance. Some companies send problem employees to counseling provided through an employee assistance program. Others bypass the formalities and discipline or terminate the employee at the onset. In most cases, disciplinary action begins with a verbal and then a written warning. If the behavior continues, termination may be a final resort. Performance coaching is an effective method for identifying and correcting a worker's bad attitude. When problems arise, employers may want to use progressive discipline that includes a verbal warning, a written warning, performance coaching, and suspension or termination. A company may safeguard itself against charges of biased treatment or wrongful discharge by establishing a written policy that defines attitude problems and that outlines how discipline will be administered.
