The anonymous online survey is being run by the Ethics & Compliance Initiative. Data compiled through the survey, collected by Qualtrics, will be used by the Hollywood Commission to develop initiatives aimed at protecting workers.

According to the commission, the survey will be open to "anyone who has worked or has tried to work in any area of entertainment", and will be "the largest attempt at gathering this essential data".

The survey aims to establish a baseline for the current industry culture to measure and evaluate future Hollywood Commission programmes; understand the extent of misconduct; identify systemic problems that support abuse of power and highlight gaps in access to representation, advocates, systems and support.

Anita Hill, chair, Hollywood Commission, said the survey had been launched in response to a need for "reliable data that reveals the specific nature and actual extent of those problems as well as the cultural environment that enables and hides them". She added: "We also want to know what is going well, and how we can improve the industry for all employees."
