Company culture is important to employees because workers are more likely to enjoy their time in the workplace when they fit in with the company culture.
On the other hand, if you work for a company where you don’t fit in with the company culture, you are likely to take far less pleasure out of your work. For example, if you prefer to work independently, but work for a company that emphasizes teamwork (or has shared office spaces), you are likely to be less happy and less efficient.
When you work at a company with a traditional management style your job responsibilities will be clearly defined, and there may not be opportunities to advance without going through a formal promotion or transfer process. At a more casual workplace, employees often have the opportunity to take on new projects, and additional roles, as time permits.
Company culture is important to employers too because workers who fit in with the company culture are likely to not only be happier, but more productive. When an employee fits in with the culture, they are also likely to want to work for that company for longer. Thus, employers can improve productivity and employee retention through a strong office culture.
