In SVT's review, several correctional officers at the country's heaviest prisons testify to a lack of security and a poor working environment.

Few want to come forward with a name and picture, because they are afraid that the criticism will lead to reprisals.

A criticism that also appears in SVT's survey, where several point to a widespread culture of silence.

Emailed after the termination

The prison guard Erika, whose real name is something else, resigned after working for several years at the class 2 prison in Kalmar.

After the decision, she sent an email to staff in which she praised her colleagues and urged management to "take care of good, experienced and driven correctional officers", while warning that "the culture of silence here is huge, and management needs to do something about it".

Shortly after the email was sent, she was informed that the offer to remain as an hourly substitute, to which she had already accepted, was no longer relevant.  

“I don't think I should be accused of this.

You pull the lead over the same comb,” said the then boss in a recorded conversation.

She was also clear that the critical email was the reason why she no longer wanted to offer any part-time work.

"Must take very seriously"

The manager no longer works at the institution or the authority. 

The director of the institution, Hans Lagerlöf, does not want to comment on Erika's case, but tells SVT that the management is working to improve the situation.  

- I haven't realized that there is a continuing culture of silence, but I can't accept that.

And we must take this very seriously.
