@MeadowL I wfh because our LA has flogged off most of its offices to plug the deficit caused by 14 years of Tory cuts.
When I worked in an office, I always left by 6.30pm because that's when the doors got locked. Now, I quite often log on at weekends or work into the evening because staffing has been cut to the bone, I'm doing two peoples jobs, I work in Adult Social Care where the budgetary pressures are huge, so lots of people are very stressed.
