Ref: NATIONAL MEDIATION BOARD REPRESENTATION MANUAL ( Page 16)
"SECTION 13.201
Telephone and Internet Voting Instructions
The Instructions consist of the Telephone and Internet Voting Instructions, and an Access Code. It is NMB practice to list the incumbent, the applicant, the intervenor, the “write-in” option, and the “no representative” option in descending order on the Instructions. If there is no incumbent and more than one applicant or intervenor, the Investigator will determine the placement of the names."
"14.305-2 Valid Ballots
Valid ballots cast for representation include “write-in” ballots
which clearly indicate the voter’s desire for representation.
Voters must “write-in” the name of a specific organization or
individual to cast a valid vote."
I don't see anyone but TWU officers doing this ...... LOL ... as far as I know you can write anything even Mickey Mouse.
