How does job satisfaction affect the creative skills of an employee?

creativity and innovation are directly affected by job satisfaction.
Recent studies on job design directed the attention of the designers that the motivational aspects of the job is very important for employees creativity and innovation.
Yet, it is also, important to know that job satisfaction is not only out of the motivational aspects, the employee might not be satisfied for various reasons, for social characteristics of work for instance, might be of knowledge characteristics.
That is why it is very important to continuously conduct job analysis to manage employees satisfaction and direct them to the required skills.

A satisfied employee is a contributing employee, it is a fact and non disputable. An unsatisfied employee will be only thinking how to make his condition better and may be looking at options for better placements also and if not then he is a source or rumors and belly aching. Thus this employee cannot contribute effectively. Thus what should be done, termination is the easiest option  but worse one too, it is better to ask what is ailing this employee and take actions to address them and help him over come the cause of dissatisfaction.

A good and mature HR is best suited for this.
