Mishka,
This isn't about jealousy or how well people train. It's about integrity.
If Peter and Marie are training as a team but only Pete's name with authorities then if Pete gets a positive swab Marie is free for the horses to be transfered to.
Two problems. Pete got in trouble...but according to you Pete and Marie were working as a team, therefore Marie would have been party to positive swab.
Next problem, Pete is now DQed and Marie is training. Are they still working as a team?
Out of sammystew's post he/she raised issue of stablehands or other workers. Sammystew said it himself...these workers are merely working FOR the trainer, they aren't training. Employees don't have the responsibilities as the trainer. No need for listing.
Point of my posts today isn't about saying some people are dodgy bastards, but about a hard area to police that needs fixing imho.
