Pros
The people and the mission to make a more sustainable world. That's it. The only reason people stay is because you work with some of the best, talented, and courteous colleagues. It's a great culture to be a part of. The second reason is the ability to influence and help reduce a corporation's carbon footprint. The bonus to working at Engie Impact is that you are part of a larger organization, Engie Group, that has a greater global impact on this mission.
Cons
To say the company is disfunctional is an understatement. Let's start with Leadership as the number one reason. The CEO is as hands-off as they come. You rarely hear from him and when you do there is nothing motivating about his speeches. The next level down doesn't know how to lead or communicate a proper strategy. Mid-level management is then left to create their own strategies after not getting direction from C-level execs. Each of the divisions then creates their own goals as they fend for themselves, instead of working to align with the overall mission across the org. There is too much work for the number of employees to make a big impact. Then you have long-tenured employees leaving for higher pay, while leadership does nothing to keep those that remain, creating a high attrition rate. Not to mention the most recent layoff is creating heavier workloads and an even greater morale issue for those left behind. The company tends to restructure every year so you never feel stable.
