Incorrect. The AMFA does use AMT's as negotiators, however they also have hired legal and financial professionals during negotiations.
"Contract Negotiations:
"AMFA hires professionals at the bargaining table to present and utilize their particular expertise. For example, in economic areas AMFA hires a financial expert; in the pension and welfare areas we hire a pension actuary. The contract language is reviewed by AMFA's legal counsel before presenting it to the company. During the course of negotiations, AMFA's legal counsel is present at the table or available by phone, fax, or email depending upon the need. Members have the ability to observe negotiations, which educates the membership and furthers understanding of what it takes to negotiate a contract."
