Vantaggi
The main pro is, hands down, the people. Ask anyone currently working at Elsevier and they'll tell you that the only reason they are staying with the company is because of the people they work with. Aside from the people, I would say that a big pro for me is getting to work in traditional publishing. As a lover of literature, getting to work with book development is a dream come true. However, traditional publishing is dying and there are CONSTANT layoffs to reflect how poorly the business is doing.
Svantaggi
Constant layoffs and restructuring due to lack of sales. People aren't buying books anymore; they are doing e-versions of everything. The pay is terrible for the amount of work that people are required to do. Employees have no faith or admiration for the higher ups. We see them spending company money like it's nothing, and then firing dozens of people at a time because we don't have enough money to pay them.
