I think there are two separate issues here. The first is about pension age, and I agree with those who feel that the current situation is very unfair, both on the young who could have the jobs of older people who want to retire, and on women who expected to retire at 60 after paying NI for decades.
The second issue is that of furlough/working. Those who are furloughed are not able to work, so I can't see any reason to castigate them for doing whatever they are doing instead. What do people want them to do?
Those who are working from home are probably as fed up as those going in to work. It is not easy to work when surrounded by home distractions. Not all houses are set up for working (why would they be?) and having other people around can make things really difficult. I do bits of consultancy (from home just now). Just having to keep everything Zoom-ready, and arrange other commitments around work-based appointments is often difficult, and I only do a few hours a week. Full-time work from home must be incredibly intrusive and isolating. In any case, as home-workers are still doing what they are being paid for, I don't understand the resentment there either.
Those going in to work are also doing what they are paid for. I can understand that it must be stressful coping with travel and dealing with the public (who may or may not be good at complying with guidance), and sympathise with that; but I don't think it is reasonable to expect to get a paid holiday just because other people's situations mean that they are not going in to their workplaces.
I could equally ask for backdated pay because I never got paid time off work outside of my holiday entitlement when at work, on the grounds that it is 'not fair' that people are getting it now. Obviously it would be considered an unreasonable request, but the logic is the same. I would have loved 'battery recharge' time during my last years at work, but didn't get them. Most people don't, although it would be great if we could build that into a new retirement deal.
I realise that this all sounds harsh, but my DIL has also worked throughout the crisis as a key worker in retail, and is likely to lose her job soon. She and my son have a new mortgage. My sister has been furloughed, but has worked in her own time to keep the company (a charity) going. She has been on 80% of her salary and used her own money for paper/copying/broadband etc, but believes in the cause, so has done it. When furlough ends she is also facing redundancy unless a massive donation comes forward (unlikely).
Meanwhile, my friend's daughter works in a well-known chemist, and has done nothing but moan from the start, complaining that others were sitting in their gardens whilst she was at work, and generally acting as though she were the only person in the country doing the job for which she is getting paid. I'm sure that she will soon be complaining that she is subsidising people claiming benefits when the redundancies kick in for those who were furloughed.
These are difficult times for everyone, and it is not a competition for who is getting the worst deal.
