Dishonest basically means untrustworthy, deceitful or insincere behavior. Dishonesty at workplace includes stealing things/information/data/ideas, submitting incorrect data, lying to your managers, and coworkers and unethical conduct like harassment or drug abuse.

Deceitfulness can be destroying for associations, with prominent cases bringing both open shame and extreme disturbance to associations and their individuals. For instance, in 1999 Lotus (CEO) Jeff Papows surrendered in the midst of discussion encompassing lies about his military record (blowing up his accomplished rank), his instructive fulfillment (increasing both the degrees earned and the notoriety of establishments went to), and his own history (professing to be a vagrant, in spite of the fact that his folks were both living). Similarly, the string of lies told by professional cyclist Lance Armstrong about his use of banned substances caused untold reputational harm to his former teammates (many of whom he wrongfully sued for libel), his sponsors, and the nonprofit organization that bears his name. Thus, the impact of workplace dishonesty in organizations can be profound. Accordingly, great time and resources are spent attempting to navigate the veracity of people’s claims in everyday work life. Indeed, controversial techniques (such as the use of polygraphs for “lie detection”), extensive research attention, and entire industries have emerged to detect and combat lying (Murphy, 1993; see Frank & Feeley, 2003 for a meta-analysis and narrative review). However, dishonest acts continue to be pervasive in organizational life: ordinary people report dishonesty in 14% of their emails, 27% of face-to-face conversations, and 37% of phone calls (Hancock, 2007; in Mulder & Aquino, 2013).

Lets have a quick view on the consequences of having dishonest employees:

1. Theft: It is a common trend where employees use office supplies for personal projects. Remember, if you don’t ask permission, it is a theft. Theft alone results in an estimated annual business loss of $50 billion, according to an article at Easy Small Business HR. The article further adds that 75 percent of employees have stolen from an employer at least once in their careers and that employee theft causes one-third of all bankruptcies.
2. Cash or any other type of financial fiddling: Employees having cash responsibility can easily steal if the company doesn’t have a strict sytem of checks and balances. Employees who are into direct sales can easily overcharge their customers and fill their own pockets by that extra amount. In 2004, small businesses suffered an average loss of $100,000 from fraud and theft, according to BusinessKnowHow.com.
3. Tarnishes the business Goodwill: In today’s world, where social media is active, any unethical report on any of the dishonest employee will tarnish the company’s image and will lead to loss of trust by its customers. A trust once broken can never be regained and same is the case with company reputation also. It is also very difficult to recover from a ruined business reputation due to dishonesty, lack of ethics, and misconduct
4. Destroys business: According to several businessmen, having the information of recognizing what is practical and what is correct makes decent business notoriety. Be that as it may, one individual can absolutely wreck that notoriety medium-term. Practicality like alternate routes, white falsehoods, and moral failures can be a contributing variable that could risk a business. Remember that the structure of an association will exclusively rely upon its uprightness. It could ruin the integrity, credibility and reputation of the business which will further lead to loss of customers, discontinued partnership, stocks falling, good employees resigning etc
