Three former US Marines who work as dog handlers say their bosses at a major security firm treat the pups as pawns in an ongoing labor battle.

The handlers filed new Manhattan federal court lawsuits last month accusing MSA Security, which patrols high-profile spots like the New York Stock Exchange, of targeting workers who support unionizing.

The new legal claims come on the heels of a July lawsuit from 10 handlers who said the company threatens to remove the beloved bomb-sniffing dogs from employees who complain about lack of pay.

Joseph Colin McWilliams and Juan B. Gomez say MSA Security sought to “make an example of them” after they openly supported the July lawsuit. New Jersey resident Thomas Brown has also sued the company for unfair labor practices.

MSA declined to comment.
