Should employees work 30, 34, 36, 37.5, 40 or more hours a week?
It is a good thing that governments discuss this (and it is not a new discussion they are having). But companies honestly should not care. Sure, there are still some jobs for which output is correlated to the amount of hours people put in. For the vast majority of the workforce though, this kind of reasoning is outdated and demotivating.
Mainly for two reasons.
First, personal and professional are nowadays as blurry as they can be. Do you get great ideas as you take your kids to daycare? Or have you ever read an email and fell into a train of work-related thoughts just before your free evening started? How do you account for that time?
Second, most jobs are about challenges and problems (or at least, they should be). Thinking that by investing on them – on paper – 2 or 3 hours more per week actually does have an impact is silly.
It probably is the case that your organisation being involved in preserving a longer working week is just an easier way to hide inefficiency and fear of change.
