Look at Contract Awareness Bulletin 21-09 on the DALMEC website. I would suggest not consenting to having your training pre-posted in PBS and I would bid as though you have a shadow period over that time period. If the company posts training after 1800E on the 4th without your consent it will be treated as a bid award error and the company will have to pay you based on what trips you could have held without the training posted.

Send a PBS Bid Inquiry if you need further guidance.
