All this company cares about is getting gross billing by any means necessary. They say OT is optional, but they push it & if you don't do OT it'll be used against you when you ask for a raise. This company is also finding "billing loopholes" to charge medicaid patients. Zynex says it prompromotes a positive worm environment but there are a few members high enough up in the company that just talk behind everyone's backs.
