Employee unit's from Loraine

[SoupCoup]

I just purchased a 93 thunderbird Super Coupe(R code)3.8 s/c. I have 5 other 1989-95 T-bird's/cougars,but this 1 has another tag beside the buck tag(on right corner of rad support)that HAS "EMPLOYEE UNIT" stamped out of it.It is painted body color & is spot welded to the support where as the buck tag is fastened with one screw(as it is on the other 5).It was produced in the Loraine Ohio plant,does anyone know if this is something they did if it was ordered by a plant worker or could have been anybody that worked for Ford?Has anyone heard of or seen this before ?It is the same size as the buck tag with no other markings on it.
