A greater number of junior workers, for example, seem to be more in favour of working in the office. According to a study carried out by the audit firm PwC in January 2021 in the US, the least experienced workers were more likely to want to be in the office more often. In this category, 30 per cent of workers with less than five years' professional experience preferred working remotely no more than one day a week, compared to 20 per cent of all respondents. 

One reason for this is productivity. These less experienced workers were more likely to feel less productive while working remotely (34 per cent vs. 23 per cent).

Remote working for these younger workers means having less contact with colleagues and managers, which could be destabilizing, particularly because in their first professional roles, young workers are keen to experience office life and to get on board with company culture. That can be difficult to achieve when working remotely 100 per cent of the time.

In France, disparities have been seen between generations close in age -- Millennials and Gen Z. According to a study conducted by Chaire Workplace Management of ESSEC Business School, 79% of Millennials were keen to carry on home working after covid-19, compared to 68% for Gen Z. The figures are certainly close, but they could reflect a desire among younger workers to get back to the office.
