Flexibility no longer

Recommend

Business Outlook

Pros

This used to be a great purpose driven company, isolated from share holder drive. There are still pockets of long term vision, but massive federation makes it difficult to achieve.

Cons

Recent changes to UK policy. What made this company great in valuing employees and being a purpose driven company is being eroded. Yes the economy is hard, but the levers being pulled reduce the huge amount of great positives that made Mars. Flexibility now being negioted, presenteeism being encouraged and a toxic environment driven by constant goal posts being moved and careerism from senior leadership. Diversity and inclusion are talked about a lot but this is another area now second to short term goals. Great long term senior leaders leaving only reinforces this.
