Candy and Philip, bus drivers for Latino Delivery, Inc., a transportation company, began soliciting signatures from other drivers to certify the Teamsters Local Union No. 777 as the official representative of the employees. Latino Delivery fired Carol and Pedro. The two drivers filed a claim with the National Labor Relations Board (NLRB) alleging that the employer had committed an unfair labor practice. (See Labor Unions)

Which employer practice defined by the National Labor Relations Act did the plaintiffs most likely charge Latino Delivery with committing?

Is the employer's discharge of Candy and Philip likely to be construed as a legitimate act in opposition to union solicitation?

If a violation is found, what can the NLRB do? Discuss.
