I can't imagine, in the face of cuts, Covid, etc why some sectors have higher sickness levels - such as the NHS, Schools, Social Care, Police?
All the services cut drastically, increase in demand, stress and pressure - it's going to cause long term issues with stress - oh and you know, pesky things like long covid?
Working from home during lockdown meant I could work when I had Covid - I wouldn;t have been able to go into the office!
