    Pros

    Huge Corporation with a lot of opportunity. A lot of the managers do work to help other move up or in whatever direction they want. Lots of opportunity.

    Cons

    A lot of the groups do have the old school mentality, where they look out for themselves instead of their employees. Also the vacation policy is a definite con.

    I worked at Johns Manville full-time (More than 3 years)

    Pros

    There are some parts of the company culture that actually happen. The overall work environment is very positive. Everyone is very nice. There is currently a lot of change planned for supply chain. This could be good, creating opportunity, or....Would have like to stay, just wasn't going to work out.

    Cons

    Despite claiming market based pay, the general consensus is that the salaries are below market. The supply chain is very flat which has led to very limited opportunities for growth.

    Advice to Management

    JM has a lot of very long term employees, particularly at the plants. But this does not so much reflect company culture at WHQ, realize the difference. 3% cost of living increases don't keep up with the rapidly rising, and higher than national average cost of living in Denver. Apartment rent alone is going up 13% per year. Realize this and act on it for the benefit of your employees. Recognize the importance of growth for employees you want to keep. Do these things and you are likely to have longer-term employees at WHQ in Denver.

    Flat management structure. Promotes from within whenever possible. Owned by Berkshire Hathaway. Invests in the business.

    Pros

    The company has longevity and is in a great location in Denver.

    Cons

    You can not grow with the company if you do not have a college degree. For employees hired within the 1990's that do not have degrees they are under appreciated, yet they have company product history and knowledge.

    Advice to Management

    Look at the employees that have stayed with JM and worked very hard, pay them accordingly.
