Do you think the UK will adopt a 4 day working week?

Its a reflection of certain jobs in certain sectors, unfortunately some roles require more than a comprehensive training course or degree to become the best, not all skills are acquired through a textbook, nor can you mark some peoples work and provide sufficient feedback without listening and observing their behaviour, full context and tone in person. A court transcript will not always provide a full picture. Again this is not all sectors, I am not in the particular field, but as an oversimplistic example take IT Support... S\*\*ts Broken -> Fix it -> Its Fixed -> Job Done; understandably in such a job WFH is probably viable as the process and results of your work are very objective and easily measurable. Contrary to the above, consider businesses like Estate Agency, indeed the simplified process is List House For Sale -> Find Buyer -> Sell House -> Earn Fee (a measurable result); however, if your negotiation staff have a very poor telephone manner generally - the transcript/file notes show they have done their job (getting the sale through) but had a sh\*\*\*y tone throughout compared to what someone with a bit more experience would take - the objective measure of success is the house sale still goes through in both cases, however, with the former the customer service will be nowhere near as good as the latter -> the customers word of mouth marketing is going to only recommend the agent they liked dealing with... leading to fewer or greater amounts of instructions - fewer instructions due to poor service is not easily measured - how do you measure a lost instruction that you never got the original lead for? Its not always what you say its how you say things or offer x as a solution to a rare hold up - you learn these skills by observing others. Similarily other professions the work is far more subjective; the best approach and optimal result are not as easily defined - take business negotiations, where you need to build rapport with customers, the aim not only to get a deal agreed (very measurable result) but also to provide quality customer service (to get repeat business) as well as agreeing the terms of the deal to be the best possible - not so measurable - as you may never know if you could get better terms once agreed. In the latter instance, as we know, people want to do deals with people they like, hence better terms tabled to agree a deal. In complex negotiations its not a case of the textbook being applied in every case, a valuable skill is identifying the character of your clients/suppliers, applying years of experience, to understand whats the best approach/tone/manner to do business with different people and adapt your procedures in order to give you the best chance of a successful business transaction. You cannot teach every permutation to take in every case within the confines of a classroom, the only way to become the best at this is by observing colleagues, taking in how they do things then adopt some things they do that you think work well and dismiss things you don't think work well into your own approach - asking colleagues questions along the way as why they said x on the phone instead of y - we are not robots, individuals build their own styles on how to deal with things by learning from how others have dealt with non-standard scenarios. To become the best at your job and open up more career progression opportunities, you need to learn from the best. The top people in your sector may be your boss/colleagues, many of the very best are the busiest people, not ones with the time available to sit you down in a classroom and give you a lecture, but by being in the same environment and shadowing their actions on the job, you are going to learn so much more than what a structured training course will teach you; if a designated trainer for a company could teach you how to become the very best at a particular position they wouldn't be training they would be doing the actual job themselves, being too valuable to a firm to underutilise their expertise. Personally, I did all the courses, obtained a degree, learnt all the academic/textbook elements of my chosen field, but I learnt far more by shadowing one of the best in the industry for 6 months than I did in the previous 5 years of formal training. What about peoples personal circumstances? We all have personal issues that occur that can affect our work life, whereby talking it through with colleagues can help, whether it be just a soundboard or taking on workload on their behalf providing a bit more breathing space. Not everyone will be as forthcoming with their issues as to call you up when WFH to discuss things; maybe because of their character or because you have WFH isolated work life, you have not built up as much as a personal relationship with colleagues as you would in an office environment; some peoples closest friends are from their worklife. Obviously some people will not be forthcoming with their issues if they are in the office or not, but if they are in the office, even though they may not say anything, a lot of the time colleagues can get a feel from your general mood that something maybe wrong - may be prompting one to ask, offer you help or just generally change the way they act in order to lighten your mood or eleveate your workload/pressure as its obvious you are going through a bad time - albeit they may not know exactly why.
