They are making sales, on the phone, emailing. Its hard to argue about because of the few measurables (10 total sales in 3 months). Just like me, they claim they are pulling their own weight. The problem is I believe them and they don't believe me.

I can point out involvement on Slack, where I am super engaged to everyone who posts and in contrast, they respond haphazardly if at all, but this gets petty.
