Yes it is, but there is a breaking point and a high turn over rate due to treatments by customers.  I bet you don;t know everything about your companies policies let alone everything about every device on Verizon's network let alone another carriers network.  I deal with phones on a daily basis and go through phones as much as the next guy, but someone who just started for a year(lucky to keep people past 2 years).  Kids today are more into I get what I want, and nothing else.  You can see it in stores from time to time, and most of the times they are no older than 25.
