Pros
Being an account manager or director gives you a lot of leeway in managing your account. Due to the nature of the business, I had a lot of independence from the higher-ups at Sodexo, where I would see my GM or DM once a month at most. Also, I really liked Sodexo back-office support. Utilize them if you need it, and they can provide a lot help to get you started. For example, reaching out to your HR department, and they can help you with the hiring. This goes for OH&S, IT, Payroll, Finance folks as well.
Cons
Your experience will vary greatly depending on the client and contract. I started in the Healthcare division and it was miserable because it was a terrible contract in an intense hospital environment. Jumping to another division, I suddenly felt like my work-life balance hit a nice equilibrium. As the account manager/director, you are squeezed between the client expectations, Sodexo senior management, and labor unions (if applicable). You have to answer to a lot of stakeholders! Also, your career is based on the life of the contract, which is the nature of the business that Sodexo is in. I think the people who are at Sodexo for the longest tends to work on the corporate office, not at the account level.
