Any reasonable method of delivery to the parties listed under
Sec. 639.6 of this part which is designed to ensure receipt of notice of
least 60 days before separation is acceptable (e.g., first class mail,
personal delivery with optional signed receipt). In the case of
notification directly to affected employees, insertion of notice into
pay envelopes is another viable option. A ticketed notice, i.e.,
preprinted notice regularly included in each employee's pay check or pay
envelope, does not meet the requirements of WARN.
