The man, who is in his 30s, secretly filmed his colleague at their offices in Skåne. He reportedly hid a mobile telephone inside a toilet and inside a change room.
The victim found the hidden phone by chance and contacted police.
Investigating officers learned that the man had a long history of abusing the woman, and over a one-year period he had repeatedly touched the woman inappropriately while on the job.
Despite her repeat requests for him to stop, the man would often continue to touch her back, legs, breasts, and behind, reported the TT news agency.
Police raided the man's home and found a further 15 films featuring the woman.
The man confessed in a district court that he had indeed filmed the woman, and touched her against her will on an almost daily basis.
He was told to pay the woman 65,000 kronor ($7,680) in damages and was convicted of sexual molestation and for breaching data privacy laws, as he had secretly looked through the woman's own mobile phone too.
The man was also convicted for a relatively new Swedish law – “kränkande fotografering” or “offensive filming”.
While the Skåne man didn't get away with his voyeuristic crimes, at least one other person has managed to escape through a loophole in the law, which was introduced in July 2013.
A young man in central Sweden walked free in September last year after a court ruled he wasn't “secretly filming” a woman in a change room because she had caught him in the act.
The court ruled that he couldn't possibly be convicted for “secretly” filming if the victim was aware she was being filmed.
