Before you go making a look how good OD is doing and how Saia is going to hell statement, you might want to read through the comments, on the OD forum, with respect to this bonus.
From what I'm hearing, Saia freight levels are decent, all things considered, and runs are being made. I would rather have Saia's interim solution; 5 extra personal days and the option of taking a few weeks of unpaid job protected leave and the no match 401-k, than $500 before tax bonus. Now, if things do go South, then you may see layoffs and pay redaction but for the time being there has been nothing like that. Let's keep our fingers crossed and let OD have their $500.
