I wonder if they meant paid COBRA of 6 months, bc 18 months is like the minimum to offer continuing coverage. COBRA coverage is a Federal Law for large employers.
"Q11: How long does COBRA coverage last?
COBRA requires that continuation coverage extend from the date of the qualifying event for a limited period of 18 or 36 months. The length of time depends on the type of qualifying event that gave rise to the COBRA rights. A plan, however, may provide longer periods of coverage beyond the maximum period required by law."
