When it is time dismissing
When the employer ceases to arrange you, it is worth considering resignation. It is important to distinguish between a situation where the company is going through a crisis, or on your relationship to the employer affected by fatigue and those cases when the working conditions become unacceptable.
Dissatisfaction with income could be the impetus to finding a new job. Guide the monitoring of the labour market. If you see that other companies employees in your area, the pay is much more, and in the plans of your leadership is not part of wage indexation, it may be time to consider jobs with other employers.
If you are determined to make a career in their field, but I see that your company growth is almost impossible, it may also be the impetus for the dismissal. Unfortunately, there are companies that do not practice the increasing professionalism and development of its staff and prefer to hire managers from the outside. Besides, there are firms in which to standing position to invite people solely on familiarity.
If you're not comfortable doing, maybe it makes sense to conceive of resignation. From the outside, might think that the position you have a good, working condition is great, but actually you can't work in the enterprise.
The reason may be that it's just not your company. If you against its corporate tradition, you don't see the loyalty to the leadership, so you will be better off elsewhere. With the team also may not be simple. And it's not you and not the people who work near you. Sometimes individuals can't work together because of differences in the principles and mentality. And this affects not only efficiency, but also on the psychological state of people.
Maybe you are uncomfortable to get to and from work. When you consider this factor a trifle annoying, but no more. Vacant post seemed so tempting, that you have decided that will cope with the long ride. In fact, everything was more difficult, and the daily suffering on the way to and from work knock you off track. Think about how to find a job closer to home.
Finally, you should decide on dismissal if you have been offered a promising job with high salary in another company. No need to cling to the old, if many criteria future work better. Believe that everything changes for the better, and don't be afraid to take the plunge.
