Trust and Honesty
Trust and honesty go hand-in-hand in any relationship, including those in the workplace. Regardless of whether you run the company or work as an intern, the workplace will be unhealthy if you don't trust those with whom you work and aren't honest with them. When an employee asks a manager for an answer, the manager should answer with honesty; if not, the manager's reputation will likely suffer. Trust and honesty are important in manager-employee relationships and almost always those between peers.
Communication
Without effective communication, numerous problems can arise in a workplace. Managers must clearly communicate the company's vision and strategies to employees, and employees must communicate any issues or difficulties in implementing measures to achieve the business's vision. A key to effective communication is to do it in a timely manner; if a manager needs to assign a task to an employee, she should do so as soon as possible to give the employee adequate time to achieve the task.
Equality
For a workplace to function effectively, equality must be a cornerstone of the company's principles. Equality in a workplace takes several forms; employers and employees alike must view people of different ages, genders, nationalities and sexual orientations as equal, and when a company hires, it should do so based on the merit of the applicant. Managers must also treat employees equally; if a manager has a friendship with one employee, she must not give that employee preferential treatment.
