Dagens Nyheter reports that the survey results were published last week but that the National Police Board chose not to reveal the criticism leveled at the management.
The survey was distributed to around 22,000 employees out of whom 81 percent responded. One section included a number of statements which respondents were asked to rate on a scale of one to 10, with 10 being the top mark.
To the statement "I have confidence in the National Police Board's management of the police force", 42 percent of respondents replied with grades ranging between one and four.
"These are poor results for the country's top police leadership," police chief of staff Elisabeth Bjar told Dagens Nyheter.
"We now have to start analysing the response. One interpretation could be that there has been a lot of focus on results in the past few years. It is not pleasant to read such negative news about your own work place week after week. I think that has affected employee satisfaction."
