A council worker feared he would lose his job if he reported an alleged sexual relationship between two colleagues, a tribunal has heard.
Tom McNeil was a senior employee at Aberdeen City Council
Scott Smart, a duty manager at Aberdeen City Council, made the claim while giving evidence at the employment tribunal of Tom McNeil.
Mr McNeil, 52, claims he was forced to quit his top job after reporting seeing two colleagues having sex in an office.
Staff traded sex favours for promotion, the ongoing tribunal has heard.
Mr Smart said staff in the office were too scared to speak in front of the female employee, who cannot be named, because they feared it would go straight back to her alleged partner Brian Woodcock.
He said: "She had the director's ear and everyone knew about their relationship, it was obvious and quite intimidating.
"I have never known a situation like that, it was the most unprofessional atmosphere I have ever worked in."
He said: "They were always together, she would be rubbing her foot up his leg or sitting with her legs across his, whispering in his ear.
"It made my skin crawl."
Mary Kearn, who is representing Aberdeen City Council, asked Mr Smart if he was so uncomfortable with what he saw why he did not report it.
He said: "The director is very high up, too high up for me to take on."
The hearing continues next week.
