What has happen in the work place?

I was walking through a hospital here in St. Louis and i seen 2 nurses both checking their cell phones.  now i don’t know if they were looking at email or a text but it does not matter. now I'm not that old, only being 29 but i remember a time when you had to worked at work.  Now you can walk through any workplace and see a number of people playing on their phones, answering emails and texting.  Work is for work and cell phones are for outside the work place. 

Now i know that if your cell phone is part of you job, then that’s ok. but if you do not need to use your cell phone then stay off and work.
