The independent standard for responsible hospitality employers, founded by Justine Murphy, has released the findings as a baseline against which it intends to measure workplace change over time.
Responses were gathered from employees and employers across the hospitality industry.
The findings show that 52% of respondents experienced inappropriate, unsafe or unacceptable behaviour during the past 12 months, while 65% said they had experienced it at some point during their career.
Of those who reported experiencing poor behaviour, 80% said it had occurred within the past year.
The research also identified a gap between workplace policies and their implementation.
Fewer than one in six respondents said they work somewhere with clear behaviour policies that are always followed on a day-to-day basis.
More than half, 56%, said they did not believe appropriate action would be taken when a concern was raised.
The survey found that 42% of respondents would feel comfortable raising a concern about workplace behaviour or culture.
