Always be on time; better yet, be early.

Ask questions! If you've been assigned a task and don't know exactly what to do, ask your Boss or a co-worker for more clarification/details. They will appreciate your interest and concern in the assigned job.

Don't take time off unless you're ill, call in and explain your
absence. Do not have someone else call in for you.

Always show an interest in the company. Learn all that you can about all aspects of the company, not just your own job.

Co-operate with your colleagues/team members and your Boss.

Most importantly, work safely. Do not hurry to get a job done at the risk of an accident. Report any unsafe work atmosphere to your Boss.

Dress formally   and cover your body properly, avoid a "catchy" look.  A person working in the fashion industry will dress differently than a person in corporate office. Take tips from your
co-workers; see how they dress.  Use minimum Jewelry.  

Accept challenges and take initiatives. Do the job you're being paid to do. Don't let your personal life interfere with your professional life. You're being paid to work.

Keep personal telephone calls to a minimum and as short as possible.

Learn to accept criticism. When your Boss or co-workers comment to you that you could do a job better or faster, recognize these suggestions as a way to improve your work productivity.

Be aware of your company's rules and regulation (i.e. Leave policy, salary procedure, overtime, delegating responsibility, sharing information et al.)

In case of a conflict with your co-workers, always be tactful in handling the situation and never make it public. Of course, if the situation deteriorates, talk it out with your boss or with the HR professionals.

Don't talk about private company matters after job-hours. Private company business should stay private.

Last but not the least, always take pleasure in your work and pursue it as your hobby.
