Doesn't surprise me at all. The company I work for had a similar survey internally and over 20% of the respondents indicated some level of harassment or coercion (fewer than 20% reported coercion or quid-pro-quo). This is a company that works hard at not having that sort of thing, being inclusive and diverse, etc. and has a reputation in the community as being one of the better places to work as far as gender and racial diversity is concerned.
