: The responsible Swiss ethical board in Bern (Kantonale Ethikkommission Bern) confirmed that approval for the ‘STRAIN’ study is deemed unnecessary according to national legislation and does not fall under the Swiss Federal Act on Research Involving Human Beings (reference number: Req-2016-00616). The study was conducted in accordance with the Declaration of Helsinki. All health employees of the participating organisations were informed about the aim, procedures, risks, benefits, anonymity of data, and alternatives for participating in the study via online announcement / paper flyer and a short explanatory video so that they could make an informed decision about participation. Informed consent was obtained and participants were again informed on the first page of the questionnaire about the aim, procedure, and possible risks and had to actively give their consent (written, using a checkbox) to continue the questionnaire. The study was carried out on a voluntary basis for all participating organisations and health professionals; all participants were free to stop filling out the questionnaire at any time and had the opportunity to contact the research team via hotline if they had any questions. Data were anonymised and analysed only in units of analysis of at least 6 participants (e.g. per occupational group or ward).
