Shop stewards play a key role in ensuring that pregnant women receive the full protections of their collective bargaining agreements and state and federal worker-protective laws. Too often, when women become pregnant, employers push them out of the job or deny them minor changes needed to continue working safely. Women are a growing demographic of workers represented by unions. Ensuring their fair and equal treatment on the job promotes goals fundamental to the labor movement – worker safety, job security, and wage protection. This manual provides shop stewards the tools they need to effectively represent pregnant workers. It provides practical tips for counseling them about critical workplace issues. It explains the laws and common contractual provisions that may assist pregnant women who have been discriminated against or who need reasonable accommodations to continue working while maintaining a healthy pregnancy. And it provides guidance on grieving contractual violations on behalf of pregnant workers. Last, it provides contact information for organizations that can provide free advice if you need more information. The laws and contractual provisions discussed in this manual provide legal rights, but pregnant workers benefit from these protections only when they are enforced. It's the job of the shop steward to empower workers and demand employer compliance. This manual is meant to guide you in educating pregnant workers and enforcing their hard-won rights.
