Can a non-member be placed in Bad Standing?

The Endeavor contract Section 21 contains an Agency Shop provision requiring Flight Attendants to become a member of the Union or pay to the Union a monthly service charge for benefits and administration of the agreement. The monthly service charge will be equal to the Union’s regular monthly dues. All Flight Attendants, whether a member or non-member, can be placed in Bad Standing for non-payment of monthly dues/services charges.
