Changing work patterns might become the norm for many jobs because of the savings for both the employer and the employee. If nothing else, the restrictions of the last three months have proven that much more home working is not only viable, but more effective. As a result, it may be that a significant part of job functions are only availble as working from home so there will be no work for those who won't accept the 'new normal'. That would be change that is desirable to the employers, partly because of their lower costs, but also because their competitors would otherwise have an advantage over them. In another time, one of the first widespread impacts of IT in offices was the removal of many secretarial jobs. The 'typing pool' was a feature of any medium to large organisation, which over a decade or less almost disappeared. There were those that complained (in addition to the typists themselves), but the imperative of maintaining competition just forced the change in.
On the travel front, I think that there will be reduced traffic for some time meaning that safe levels of separation vs some new level of revenue will be around for 2-3 years, and it will be encumbent on the government to manage that - not only from the simple cynical capitalist 'profit at all costs' angle, but also as the impetus of greening transport really gathers.
