Something like what you posted, without the harshness, from those guys that get that big chunk of your paycheck, maybe??

"Guys and gals...we're working with the company to make sure the training letter, when posted, will be accurate, and something you can use for planning your strategy and personal life. We know this is inconvenient, and apologize for the delay. Our concerns involve xxxxx and yyyyy. We anticipate that the training letter will be posted mmddyy. Thank you for your patience."

Maybe???
