Svantaggi
They are focusing alot on cutting costs from time to time. People do not get properly compensated for their hard work as a consequence. They prefer that older (more expensive workers) leave the company and are replaced by younger (cheaper) people. Sometimes they feel this is not enough so they try to ship whole departments to low wage countries. Career opportunities are limited. It is easy to get trapped doing the same tasks without advancing. You have to stay hungry and search for new opportunities yourself. It is too much politics and silo mentality preventing people from performing well.
