OP I think you've been given a really hard time here.
I understand what you are saying, entirely. I am furloughed, my employer are not topping us up they have told us that we are obligated to undertake 50% of our hours as training. They said they'd like us to do more, but they were advised that as we are all paid so little, we may end up dipping below nmw.
I would love to be at work. In daft I'd happily work from home. My job is essentially still there, but my employer would rather have the money from the government as my office role is funded by the wider business which isn't currently revenue making.
I am happy enough undertaking training, in principle. However, as they will not pay for any training, we can only do courses which are free, or paid for ourselves and which directly benefit the business. For example I suggested a course that would be interesting and offered to pay for it myself, I was told that I could do it in my spare time, but as it was not directly relevant to my role, it wouldn't count towards my 'hours'. It was entirely rekevant to the business, albeit a paygtafe or two above me.
The free courses are, in general low quality and short. With no beneficial information, CPD points or actual qualifications. My direct manager is on the senior team and he admits that there is little benefit, but he can't stand the idea of people doing nothing.
Never mind that all, yes ALL my colleagues are volunteering for the local community groups and helping individuals who are also our service users (we are a charity). I would suggest that allowing staff to spend more time doing this and raising the profile of the charity would actually be more beneficial.
My husband is working full time at home (on a reduced salary) and we have two children of an age where they are homeschooling and need constant support. We have timetabled the day to allow both of us to get work tasks done. I'm focused and enjoy learning and despite this, it is STILL hard to stay motivated, under taking low quality, independent training that you know is unlikely to benefit anyone.
You could all do with fmgetting off your high horses.
