Pros
One of the pros I have with Zayo is that it is a company full of hope and optimism. It seems like everyone has high hopes which is a good thing. It makes you feel like you have a part in this new type of company. I do agree with most of the reviews posted when they say there are great people with many talents. Many of them are very willing to help out when asked. I would have to say that the biggest Pro for this company is their talent in the field. Those guys are always putting their lives on hold to help out in an instant. I can't say enough about them.
Cons
On the same note as above, the biggest con would be that the guys in the field do put their lives on hold to help out in an instant. Sometimes in part to fear of losing their jobs. I have worked with Zayo coming from one of the original acquisitions. So for me its been a long time coming. But the raise in salaries is horrendous. I have not seen a raise. I feel that there are likely others in the same boat. You make of that what you want. I also agree that the 401k is dismal. But sounds like that will be changing soon.
