Final answer:
The Civil Service Reform Act of 1978 does not expressly prohibit management from assisting a labor organization, but primarily aims to ensure a nonpartisan federal service by enforcing merit system principles.
Step-by-step explanation:
Under the Civil Service Reform Act (CSRA) of 1978, management is not expressly prohibited from assisting a labor organization. Instead, the Act reinforced merit system principles and created agencies to oversee them, such as the Office of Personnel Management and the Merit Systems Protection Board.
The Act had several provisions, including making it illegal to fire or punish government workers for strictly political reasons and raising qualifications for employment in civil service. However, it mainly prevents federal employees from participating in certain political activities, reflective of a continued push to maintain a nonpartisan federal service.
