I'm going to disagree with
@SrTLall. Every effort does not mean none. The handbook is the contact with the employee and would fall under effort provisions. In actual use reasonable effort and every effort would be synonymous. The only way none would apply is if it was due to a force majeure (power outage, hurricane, etc). That's why I tell TMs to have their cell be the primary point of contact so they can have both a message and a call log. If they don't even call you no attempt was made.
It can be a ASANTS, and there will with out a doubt be pushback if the store hasn't had anyone pay attention to the handbook, but it's one of the things that if you document you can go to the hotline with, so document, document, document and show up in the store. They are going to try to hold you accountable if you don't show up, this is just your side of the coin in keeping them accountable.
Target has very specific ways they are to ask a TM to leave so that it's considered volunteering.
