With the rechargeable battery pack being inserted, as the first mirrored-L shaped tab passes over the catch of the spring loaded latch, the catch of the spring loaded latch is depressed into the charger. After the end of the first mirrored-L shaped tab has passed, the catch of the spring loaded latch is released to protrude up behind the first mirrored-L shaped tab in order to hold the rechargeable battery pack to the battery pack charger. To release the rechargeable battery pack from the battery pack charger, a user depresses the button of the spring loaded latch to depress the catch so the first mirrored-L shaped tab can clear the catch as the rechargeable batteryfollows.  In 1958, following a close election in which it received slightly more than a majority of the votes, the Union was certified by the Board as the collective bargaining representative of the Company's production and maintenance employees.  On July 2, 1958, the Company and the Union executed a collective bargaining agreement which provided, among other things, for a limited form of union security.  Under the agreement, non-members of the Union employed by the Company were not required to join the Union.  However, members and employees who thereafter joined the Union were obligated to maintain their membership for the duration of the agreement; new employees were required to join the Union after thirty days' employment.
