Ethics means applying principles of right and wrong to decisions and behaviour. There are many ethical issues related to work:
Your integrity governs how hard, well, and consistently you work. To succeed in the workplace, you should exhibit a high level of commitment to getting the job done. If you work hard even when you are not being supervised, your employer will trust and promote you. If you work well only under supervision, you will not be trusted or promoted. If you waste time slacking off, you may not last long. You should not only work hard, but also control the quality of your work. High output with lots of mistakes and defects is as bad as low output.
What you value determines your goals in your work. Your ambition drives you to attaining these goals. Some people are willing to compromise ethics and values to attain their goals. They believe "The end justify the means." However, the best policy is to maintain a high standard of ethics even if it may delay realising your goals. For instance, you could deceive a customer to make a sale and get a higher commission, but the customer will probably be dissatisfied and return the merchandise.
People with high ethical standards live by their word. When you speak to others, you should make sure that what you say is true as far as you know. Do not give the impression that you know an answer when in fact you do not. Never make up answers to questions. You should avoid making promises you cannot keep. And you should never lie to supervisors, co-workers or customers to save yourself.
While at work, you should respect the property of your employer, supervisor, co-workers and customers. You should not steal or damage things which do not belong to you. If you need to borrow something, you should inform the owner and return it promptly when you have finished. You should not abuse your employer's resources, nor use workplace equipment for personal projects without permission.
People with high ethical standards show respect for supervisors, co-workers and customers. They do not use others to attain their own goals. They avoid listening to or spreading gossip. Sexual harassment is the unethical practice of using power in the workplace to achieve sexual favours. It is a form of disrespect which demeans the victim.
With high ethical standards, you will respect and follow authority if it directs you in an ethical way. However, you could face a tough decision when those in power pressurise you to violate your ethical standards.
