I work in the NHS in an office based job and have been in the office throughout, we have a WFH rota, which is mainly to do with insufficient desk space as the team has grown significantly to deal with the workload. I don't have a problem going to the office, I'd hate to be stuck at home every single day, not having real human interaction or chat. Being able to leave the house and go to work has helped keep me sane this year. Oh, and it's only this week we've had the first positive covid case for anyone in the team.
My husband has WFH throughout the last 18 months and has been thoroughly enjoying the ability to leave the house and go to the office over the last few weeks. Most in his place are still choosing to WFH though, my husband is a senior manager and the company approach is going to be a hybrid model, probably two days in the office and many staff are complaining about even that. Frankly it just comes across as lazy, when the rest of society is open and presumably everyone is happy to go to shops, pubs, restaurants, parties, sports matches, any other large public event. Just as well those staff are prepared to get out their onesie's and actually leave the house for work. I get that many people feel the benefit of no commute, but it's increasingly looking like a middle class pandemic where office workers on secure salaries want to sit at home while the rest of society on low, unsecure wages trudge out to the house every day to ensure the Amazon deliveries keep coming.
And remember, if your job can be done fully remote anywhere in the UK, it can be done anywhere in the world for a cheaper wage.
