Pros
The culture is laid back and mostly positive. High goals are set and attained through team work. Most people seem happy with their positions and there is not a lot of politics and infighting, at least not to an uncomfortable degree.
Cons
Some procedures are undocumented or poorly documented, leading to confusion. Different software and procedures and parts exist for each product line and are often wildly varying in the way they are made or used or data is managed. Seasonal nature of all oil and gas industry jobs leads to a high percentage of "seasonal" workers, temps who receive different compensation and less benefits, although they are semi-permanent and our hiring pool. It leads to difficulty in retention and in attracting qualified people.
