Who I have the same questioned this topic

I switched to Verizon a little over a year ago because I wanted better service. One of the places I was hoping to have fast and reliable services was at work. For a while,  had just that. Recently I deployed and since I have gotten back, my Verizon service while at work has been incredibly slow. So slow that my phone is useless for periods of time. My phone works great everywhere else. Except for when I am at work. Other coworkers that have Verizon are experiencing the same problem. I don't know what to do.
