Love your job, be honest and trustworthy, handle affairs fairly, serve the masses and contribute to society. The meaning of professional ethics includes the following eight aspects: (1) Professional ethics is a professional norm, which is generally recognized by the society. (2) Professional ethics is naturally formed for a long time. (3) There is no definite form of professional ethics, which is usually embodied in thoughts, habits and beliefs. (4) Professional ethics depends on culture, inner beliefs and habits, and is realized through employees' self-discipline. (5) Most professional ethics have no substantive binding force and coercive force. (6) The main content of professional ethics is the requirements for employees' obligations. (7) Diversification of professional ethics standards means that different enterprises may have different values. (8) Professional ethics bears the corporate culture and cohesion, and has far-reaching influence. Every employee, no matter what occupation he is engaged in, should abide by ethics in his professional activities. To understand professional ethics, we need to master the following four points: first, in terms of content, professional ethics should always clearly express professional obligations, professional responsibilities and ethical standards in professional behavior. It does not generally reflect the requirements of social morality and class morality, but the requirements of the special interests of occupation, industry and even industry; It is not formed on the basis of social practice in the general sense, but on the basis of specific professional practice, so it is often manifested in the unique moral traditions and habits of a certain profession, and in the unique moral psychology and moral quality of people engaged in a certain profession. It even causes differences in the moral outlook of people engaged in different occupations. As people often say, someone has "military style", "worker character", "peasant consciousness", "cadre style", "student taste", "pedantry" and "businessman habit". Secondly, in the form of expression, professional ethics is often more specific, flexible and diverse. It always starts from the reality of this professional communication activity and adopts systems, codes, agreements, promises, vows, regulations and even slogans. These flexible forms are easy to be accepted and implemented by practitioners, and it is easy to form a professional ethics habit. Thirdly, from the perspective of adjustment, professional ethics is used to adjust the internal relations of employees and enhance the cohesion of employees in the profession and industry; On the other hand, it is also used to adjust the relationship between employees and customers and shape the image of employees in this industry. Finally, from the effect, professional ethics can not only "professionalize" the moral principles and norms of some societies or classes, but also "mature" the moral quality of individuals. Although professional ethics is formed in a specific professional life, it is by no means a moral type that exists independently from class morality or social morality. In class society, professional ethics always exists and develops under the restriction and influence of class morality and social morality; The relationship between professional morality and class morality or social morality is the relationship between generality and particularity, and the relationship between individuality and individuality. Any form of professional ethics embodies the requirements of class morality or social morality to varying degrees. Similarly, class morality or social morality, to a large extent, is expressed through the specific form of professional ethics. At the same time, professional ethics is mainly manifested in the consciousness and behavior of adults who actually engage in a certain profession, which is the mature stage of moral consciousness and moral behavior. Professional ethics, combined with various professional requirements and professional life, has strong stability and continuity, forms relatively stable professional psychology and habits, greatly changes people's conduct formed in school life and juvenile life, and affects the moral outlook of moral subjects. ]
