I have a problem, I passed my probation about 2 weeks ago (been at my hub for almost 4 months) and now our full time manager/supervisor or something has been on my case about my performance. i unload about 900-1100 boxes per hour on average and my supervisor normally doesn't say anything to me because I keep a good pace and get stuff done on time. or at least my supervisor doesn't say anything to me specifically. but the full time manager has been saying that if i don't step it up then they are going to stop letting me come in to work and apparently he has been telling other people i work with that they are going to fire me if I don't step it up soon. i'm already passed my probation and I don't think he should be telling other people this? I'm wondering what i should do
