If your check is more than 5 business days late call your attorney's office to have them inquire the status. If they won't follow through ask if you have permission to contact WC directly via letter asking about your missing check. Unless they've notified you of cessation of TTD, assume your benefits are ongoing. Send the letter via fax or certified mail, so that you can keep a record. I'm in a different state, but the WC laws in this circumstance seem similar...
