Recently, workers have been organizing at rapidly increasing rates. It is estimated that in 2018, 485,000 people partook in strikes involving work stoppages. Additionally, public support for collective action has increased tremendously. The Protecting the Right to Organize (PRO) Act has recently been introduced. It aims to protect employees from intimidation tactics used by employers to diminish organizing efforts. The Act would establish a process to ensure that unions are able to negotiate their first contract in a timely manner, prohibit permanent strike replacements, provide support to striking employees and penalize employers for failing to abide by labor laws.
