Can anyone help. When doing Risk Assessements, should they be basic or should they be comprhensive?

Can they contain Risks such as 'low morale' or should this be left out of Risk Assessements?

Many organisations use a risk assessment type processes to evaluate any sort of risk to the business, taking into account things like organisational reputation and threats posed by business rivals. There is nothing wrong with that and something like poor morale fits well into that approach. On this forum most of us have an Occupational Safety and Health background, we tend to look at the risk assessment process from a different point of view, namely risks to the health and safety of our employees and others. The legal requirement is to manage those risks via risk assessment. 

As we have said many times, risk assessment is process not a form or check list, which asks are we running our business  in the best way possible to ensure the lowest risks to our staff. Some organisations, that are based around a single process could conceivably assess the business as a whole and produce a single document describing this. Others which carry out loads of diverse process would find it easier to have multiple risk assessment document for each process or group of processes. I look after H&S in a University where we carry out research. We can’t really create a single risk assessment for research as research consists of  variety of things for pure library based research to labs using, chemicals, biological agents, X-rays lasers   and machinery. Others work off campus doing social research in the community and others do surveys using drones in East Africa.

The key thing is that the risk assessments are “suitable and sufficient” , the format depends on what you are doing and where you are.

Given the assessment identifies the risk and from that the necessary controls caution should be used in listing matters that can be extremley unique to an individual at a specific time and date.

If you do want to go down this rabbit hole (perepetual re-write to reflect changing circumstance) consider that for example depending upon the day in the pay cycle morale may be low or high, approaching or just after a holiday high morale may wane inbetween.

The day after a below inflation salary increase is normally a low morale day.
