So, at the Laredo TA, the same identical "E" sometimes means "employee" and sometimes means "expediter" and sometimes means "either" or "everyone" or, maybe its a grade like almost failing (for the worst parking spaces along the perimeter). Or maybe its just plain STUPID!
The real story is the coporate policy that established the "E" program has been changed locally into whatever the local manager wants and we expediters are left wondering what clowns thought this up and then bailed on the resulting circus it created when local managers found problems (like straight trucks backing into fences and knocking them over).
