I don't recall anything in the comic stating that anyone would be forced to do anything they didn't want to there, just that casual workplace sex was allowed and encouraged on the job.
The only people to have expressed any bit of displeasure with the situation at all was a single person whose anger was shown to stem from the other person having fucked up and made her job harder than anything else, and the main character who herself is more just not used to the entire situation than actively against it.
Hell two of the girls had a sexual kiss with each other earlier in the comic, neither having asked or demanded it. Just something both did and enjoyed.
Whether the comic is enjoyable will vary from person to person but the complaints about this seem to be getting to a silly place with people pulling conclusions out of thin air to complain about. :/
