Enjoyment at work is so important, yet probably only a minority of people regard their employment as enjoyable. If you work in a business sector which you dislike, for whatever reasons, get out as soon as possible and choose a career in a sector you will enjoy. If you really dislike the values and the culture of your company the same advice applies, get out as soon as possible. Unethical business standards, sexual harassment, bullying and such like are simply intolerable.
If you are happy with both the sector and your company, you may dislike your present job. Recognize that companies do not want to lose valuable staff, so talk to your immediate manager to initiate a request to obtain another job in the company.
Whilst there are some aspects of nearly every job which are not particularly enjoyable, do talk to your immediate manager in a positive way if there are parts of your job that you dislike. Do whatever it takes to maximize your enjoyment at work.
Stress is personal and subjective. You may find your job unacceptably stressful whilst your colleagues find the work stimulating. Do not suffer in silence. If the volume or type of work is stressful to you, talk to your immediate manager about reorganizing your job or an internal transfer. Stress threatens your health and must be tackled promptly.
