Air carrier Captain reported a hard landing and a safety concern with a new hire First Officer. The Captain determined the landings were not safely executed and recommended additional training for the new hire First Officer to the company. The Captain followed up and discovered that the new hire did not receive additional training and had continued flying since the recommendation.

Narrative

This report is regarding the safety concern I have over the training; checking; and monitoring of new hire pilots being released to line operations with non-check airman captains. I recently received a phone call from a fellow Captain; in my domicile; to warn me about the new hire I was about to fly with. He said he only flew two legs with them but described their airmanship below 500 ft. on approach as essentially ugly." Being that he only got to observe the person in question on one leg as the pilot monitoring; he felt it might have been a one off but felt compelled to warn me about this being that I was about to fly a trip with the new hire in question.To put it bluntly; while the new hire had a good personality and was a pleasure to be around for the few days; their airmanship was weak and their landings in particular were indeed "not pretty." Frankly; I was shocked that a Check Airman would have signed them off of IOE. The last landing of the trip involved zero flare; a VERY firm touchdown and bounce which is the point where I had to take control of the aircraft. It was so hard in fact; that my headset slid off and one of my headset cups was even knocked off. The passengers and FAs (Flight Attendant) were quite alarmed. At the end of the trip - this was the last leg - I politely informed the FO (First Officer) that I couldn't not say anything about their landings and that they'd probably need some more IOE or simulator time. I made some calls to Union and subsequently my Chief Pilot; in an effort to get this new hire some additional training. Union advised me that I'd need to contact the Chief Pilot who asked me to fill out the probationary pilot form and to be as detailed as possible about where the deficiencies are.After doing so; I watched the new hire's schedule and noticed that they did not get any additional training. They were never paired with a Check Airman; and they seemingly were never brought down to ZZZ for additional simulator training. This is deeply concerning; as the pilot in question was simply not proficient enough to safely be performing line operations at Company. At the risk of interjecting emotion into a report; I'm floored that this person was actually signed off IOE and that they were subsequently not brought in for more training; after more than one Captain had a problem with their proficiency level. Their landings were simply not safe; and our crews and passengers should not be subjected to such things and deserve better.If indeed this person did not receive additional training after both the training committee at Union and the Chief Pilot were advised of their clear lack of proficiency; then it is a colossal failure of our safety system. Personally; I do not feel compelled to fill out any more reports because 'what's the point' and I refuse to be doing the job of a Check Airman as I am neither compensated nor trained to do so. Instead; I will be refusing to fly with anyone who is released off of IOE; before they are ready. Furthermore; it's very troubling to see that when a safety concern is raised; it is seemingly ignored. Perhaps I don't have all the information on whether this new hire was sent back for additional training; but from the research I've done that certainly seems to be the case."
