What do you think some people were exempt from military service during world war 1

The British Government introduced conscription in March 1916 because voluntary enlistment could no longer meet the army’s need for recruits. Under the terms of the Military Service Act, all medically fit single men between the ages of 19 and 41 were deemed to have enlisted in the armed forces on 2 March.  

In May 1916 a second Government act extended conscription to married men and the age limit was lowered to 18. Conscripted men had no choice about which service, regiment or unit they joined.  

However, some men were exempted from the draft. Clergymen, teachers and some classes of industrial worker were not required to join. These roles were described as ‘Scheduled (or reserved) Occupations’ and included coal miners, doctors, and those working in the iron and steel industries which produced vital ammunition and equipment for the war.
