Pros
Opportunity to work from home -- many people are remote and you do not feel left out because of it. Lots of good clients. Seems to be a stable company, especially now that it is owned by ADP. Many of the people are super nice and are very talented at what they do. You will learn a lot and will have great training available to you. It is good to work for a company that is so respected. People take pride in their work. It is a great place to work if you want a well paying job where you can work from home. Your job satisfaction will depend on what client you support. Some of the accounts are just less enjoyable than others. Plus, some managers are better than others. You might like your job so much and then see it change quickly. They really offer great service to clients and are very good at what they do.
Cons
Work/life balance is hard to maintain. Just when you get a handle on something, you are asked to take on more. Since being bought by ADP, the company lost its warmth and many of the perks. Before, the vacation policy, paid benefits, perks like a big Christmas party, prize giveaways, and summer hours were awesome. Now the vacation policy is very standard and it seems that every penny is closely managed. The "fun" is gone from the company and it feels like just a job now. They used to send weekly memos and praise people and tell you what is happening in the company. That has stopped. While there is a ton of training you can take, it can be hard to fit it in because you are so busy. Also, the sales people set up the contracts with so many expectations that it is almost impossible to every deliver what they promised. All of these cons do not over power the good things about working for The RightThing. It is just sad that so much changed when everything was just a happy, happy, joy, joy place before it was sold. It is still a good place to work, but these things just detract from that.
