Pros
Great benefits. I work with a great team (this is very personal and micro), but something that I love. Good work-life balance. I usually work 40 hours per week. Maybe 10 times I've had to work overtime in the past 1.6 years. It is important to note that Adecco is a company that keeps you busy. There is always work... way more work than one can handle.
Kontras
Sometimes leadership is unresponsive and does not follow up with promises (especially relating to promotions, salary increases, projections, among other things). Adecco chooses to work with many clients that do not treat their employees well. This makes a recruiter's job harder, since you're offering a job that is not good with a company that usually has a reputation that is obvious when researching online. CEO pressence is also non-existent.
