Pros
Fluor is the largest American construction firm, which can be a source of pride to work for the biggest. It is well respected in the industry for the most part. It has a highly diversified international portfolio of projects, which allow it to stay strong and grow, even during economic downturns like our current one. This consistency provides a feeling of job security, which is nice. Working internationally can pay well. The retirement program seems good by industry standards. The 401k matches dollar-for-dollar up to 5% of pre-tax income, and they also have a small pension plan in addition to the 401k.
Cons
Downsides are the company is too big for its own people. Communication between management and employees is very poor, at least in the locations I've been. A lot of employees simply feel lost in the masses. This lack of communication means there is a lack of career development for many people. Working in the home office, it appears you can have a decent work/life balance. Working on projects in the field, forget having a life outside of work. The pay in the field is not very good when you calculate it off hours actually worked. Good bonus structure and performance based incentive plans are severely lacking.
