Let me just warn you… I know somebody who was in a office and there wasn’t enough work for her to do. Having nothing else to do, she started talking to other people in the office (including boys) and saying jokes (including not such good jokes). In the end, she was asked to leave.
If you have nothing to do, try to clean your desk or type something that you think will be helpful to the office/company.
WHATEVER YOU DO, DON’T DISTURB OTHER PEOPLE’S WORK AND REMEMBER THE TZNIUS ISSUES.
