Goodwill Industries complaint: Funny business

I have a relative who was only trained 2 days before they was let go to work by themself . For 90 days they did as they was told , after their 90 days they are getting yelled at as well as the other new employees that things aren’t being done right because they are missing a few steps when posting. Things that weren’t even taught ro them they are getting blamed for and now they are being told that if there are any more mess ups they will start taking numbers off their insensitive. Im not understanding how is this fair for them and other new employees. I truly feel as if this isn’t a well organized and professional place . People’s personal business Is being put out there by managers and supervisors. Also they were told that if shipping is behind they would hold the persons check depending on who cause the delay . Is that even possible? This job is cause alot of emotional distress as it is
