Generally, supervisors have a right to expect employees to come to work with a reasonable degree of regularity. When employees miss work repeatedly, companies take a substantial loss in productivity, which in turn, can affect their profits.

Employers recognize that substance abuse in the workplace can often lead to absenteeism, tardiness, sick leave, increased safety risks, and overall lower productivity.

An employee who complains, argues, or gossips excessively in the workplace can be disruptive to a company's environment. Oftentimes, such negativity translates to poor job performance and can also lead to the spread of low morale in the company.

Whether it's about their clients, finances, business methods, or products, every company has valuable information that it wants to keep confidential in order to protect its business interests.

Though there are no federal or state laws prohibiting employees from dating each other, there are also no laws preventing companies from forbidding employee dating, especially between managers and their subordinates.

Companies recognize that the type of clothing their employees wear affects the image they're promoting to their customers or clients. For example, employees of a surf shop may be outfitted in tank-tops and shorts all year round, while the law firm next door requires strictly suits and ties.

For employers, disciplinary problems occur when an employee continues to violate or ignore work policies. Though it's generally in their legal rights to terminate an employee at any time for misconduct, companies might want to allow a problem employee multiple chances to correct his or her behavior before resorting to termination.

Workplace violence, a substantial contributing factor in occupational injury and death, has become one of the most important safety concerns for employers.

Insubordination occurs when an employee deliberately refuses to obey or carry out a reasonable order from a superior. This type of misconduct in the workplace can obviously damage an employer and employee relationship.
