Pros
There seems to be a wealth of training material available but I am working too much to be able to take advantage of it. Ericsson places greater value upon education than real world experience so it is a good place for recent college graduates.
Cons
There is enormous pressure on managers to utilize the workforce 100%+. However, there is little respect for these hard working people in the field. On call is mandatory and when you are on call you DO get called - alot. The workforce management system sees to that. Work is delivered via your smartphone and you never know what you're going to get. Often tasks are beyond the ability of the technician as no training is offered and the system does not take individual skill sets into account. "A tech is a tech" is a term I hear quite often. We were recently "absorbed" by Ericsson from a large U.S. telecom carrier so my views may swing more negative than most.
