If you do not have a team, you still do not need to give up. Individual people can have a profound effect on an organisation, if they are willing to spend the time and the energy. This is a great example of your bread cast upon the water coming back as a ham sandwich (see the John Crabtree story at the end of Chapter 2). Behaving in great company style with everyone you encounter through the day will have an impact on the workplace. Act as a networker, introducing people who have common interests, whether at work or home; be interested in how people are - make them feel valued; congratulate when you hear about achievements. You will make a difference, and it will help you move forward in your career because you will be seen as a positive force in the company.
Since it can be hard to keep up your enthusiasm alone, take every opportunity to talk with like-minded people. Depending on the size of your organisation, you may already know where your ‘soul-mates' are. If not, perhaps you can write something for the company magazine about the list and see who responds. Ask about for people who have the same ideas about management, or go outside to conferences or seminars to top up your ideas and enthusiasm.
If your work environment is so negative that you fear a punitive response to any of the above actions, it may be time to look for another job. Weigh up the pros and cons and decide whether the cost is too high if you stay or if you leave. This may be a good time to look for one of the great companies and take your energy where it will be appreciated. Or it may be that life holds enough challenge at present and you ought to stay put. Be honest and take care of yourself in the best way possible. Just remember that there are options out there for a really exciting place to work, when you are ready for it.
