   • 2018 May 31, Jenny Kallin, “Stockholm inför dubbelt natt-OB ”, in Vårdfokus:

     Dubbelt OB, som arbetsgivaren nu väljer att sätta in, ser ut att lösa de flesta treskiftstilläggen som finns idag, Men helt nöjd är hon inte. För det första vill hon att dubbelt OB ska in i kollektivavtalet och inte vara ett villkor som arbetsgivaren har möjlighet att plötsligt säga upp.

     Double unsocial hours supplement, which the employer is now choosing to implement, seems to address most of the current three-shift supplements, But she isn’t completely satisfied. First of all, she wants the double unsocial hours supplement to be included in the collective agreement and not be a condition that the employer can suddenly terminate.

   • 2021 June 23, Per Hagström, “Så vill arbetsgivaren ändra ob-tillägget ”, in Polistidningen:

     Förutom att höja ob:et vill ni använda de 360 miljonerna till den nya Kuvsystematiken för poliser som jobbar lokalt i yttre tjänst och för att höja ingångslöner för poliser i Stockholm.

     In addition to raising the unsocial hours allowance, you want to use the 360 million for the new career and development pathways system for police officers working locally in field service and to raise starting salaries for police officers in Stockholm.
