The relations will be good always. The difference may come in the views of the person on a particular issue. Whatever we talk or discuss will be based on that point only and we will never have any personal enmity with our colleagues either seniors or juniors. When there is a discussion on any subject, the point made by all the participants will be taken with respect to that particular only. Nothing personal in this. There is no second opinion about this. If we conduct our self in the above way they there is no chance for doubts.
In the employee, if the employer has no faith, continuing in that job by the employee is very difficult. So it is the responsibility of the employee to work in such a way that the employer will never lose faith him and will never doubt him. If the employee has no faith in his employer or having some doubts about the employer, he has to look for an alternative and leave the present job once he got another placement.
