He added that employers should consider staff staying home "where feasible and possible, the Met Office guidance does state that it is not safe to drive in these conditions".
Monson said that "some people have to travel and that is understood, however where it is not essential , people could stay at home and work from home".

This is the first red warning issued for Northern Ireland since a new impact-based alert system was introduced by the Met Office in 2011.
It is also the first time a red warning has been issued across the whole of Ireland, with Met Éireann issuing the highest level alert across the Republic.
The storm is set to bring severe winds of up to 100mph along some coastal areas, while gusts of up to 90mph could affect inland areas, bringing dangerous conditions.
Any clean-up operation from the storm could also be hampered this weekend with a further wind warning issued by the Met Office for Sunday.
We're expecting a Northern Ireland Executive press conference to take place in about fifteen minutes.

Tomorrow's storm will be the first time that the entire island of Ireland has been covered in a red weather warning.
In the Republic of Ireland the red alert comes into effect at various times from 02:00.
Met Éireann has warned that "severe, damaging and destructive winds" are expected.
Speaking to RTÉ, chairman of the National Emergency Co-ordination Group said Storm Éowyn would "probably be among the severest storms" Ireland had ever seen.
Similarly to Northern Ireland, all schools have been told to close.

Image source, PA MediaThe Education Minister has announced that all schools in Northern Ireland have been advised to close on Friday
The biggest disruption so far confirmed for Storm Éowyn is that all schools will be closed in Northern Ireland on Friday.
Education Minister Paul Givan said he understood this decision would impact the work of schools and other businesses, but that "the decision has been taken to avoid any potential risk to life for children and young people as well as staff".
"Schools should put plans in place today for remote learning so that pupils can study at home.”
The last time all schools in Northern Ireland were advised to close because of weather was due to Hurricane Ophelia in 2017.
The weather warning will come into force across Northern Ireland from 07:00 until 14:00 GMT on Friday.
The Met Office says it means dangerous conditions with widespread disruption.
It advises people to expect:
It is the first time a red weather warning has been issued for Northern Ireland since an impact-based system was introduced in 2011.
Previous red warnings were issued on a different basis.
The system is also different from the one used by Irish meteorological service Met Éireann, which issues warnings based on a threshold system (more on that in a bit).
