    I have been working at Calpine full-time (more than 10 years)


    My experience with Calpine, through it's management team, has almost always been very positive. It is a company that respects and supports it's employees. Great wages and benefits. Opportunities for advancement are there for people who are willing to put in the effort and persistence. It is a company that you can have a career with.


    Not very good name recognition. When I say I work for Calpine, most people make me repeat it twice and then spell it.

    Advice to ManagementAdvice

    Keep up the good work. Focus on taking care of the employees, and they will focus on taking care of the company.

    Positive Outlook
