This is funny....I have heard the GPS story or something like it in every single animal health company I have worked for in the past 10 years.
Here's the deal...coming from management in my last company there are way too many costs associated with this, but does it really matter? This is a small business and if you arent working everyone in your area knows anyways. I work for MWI but I can tell you who in Abbott, NLS, Lilly, Webster, Vedco, Butler....name one.... works in my area. Plus, why does it matter? If you work...you get paid on your sales. If you dont work you dont get paid and everyone who cares in your company knows it. It's a pretty simple equation!!
