In around 35 years as an ATCO I never really felt stressed at work; in fact I was often at my calmest whehn working. Among my colleagues I knew of many who were the same and others who got badly stressed. Other things do stress me - like public speaking, for example. Standing up in front of only half a dozen people absolutely terrifies me to bits and I cannot begin to understand how schoolteachers manage.. I also get extremely stressed over family health. Going on holiday freaks me out, until I am on the aeroplane..
Stress affects different epople in different ways. An AME explained it to me once by saying that when I was working I knew I was in control and confident of handling any situation. In the other situations I mentioned there are other factors beyond my control and that's what stresses me out....
