Yes, he gets 4+30 for each day of training. Been there, done that. Guys do it all the time to maximize their pay.
The other option is to protect min days off during the first month and have trips dropped, but you will still get the 4+30 for the training days the first month.
If guys had been going to ITU for the last year and a half and hadn't been getting paid for it, we'd be hearing about it in a big way.
In any case, don't take my word for it. Call your F.O.S. or ACP on Monday.
