Pros
I love the fast-paced challenging environment. If you work hard and remain consistent in your efforts you will be promoted. ESI offers opportunities to employees with experience and having a degree is not required to work your way up. I like that they prefer to promote from within and value practical job experience within the company. The environment is one of fairness and equal opportunity and all of the supervisors and managers that I have worked with have been very approachable and quick to help when a problem arises.
Cons
It is difficult for some to get used to having your schedule micro-managed down to the minute as is the case with entry level positions. For positions which require the individual to field phone calls 8 hours a day, it can be very stressful and sometimes emotionally draining. You are the sounding board for people who are affected by corporate decisions which often affect their health, decisions that you may or may not agree with personally and are often subjected to wishing there was more that you could do to help.
