Identifying what a healthy work-life balance is integral to having long-term career happiness. PhDs find themselves with poor working hours which comes at a cost. Certainly, work-life balance should be a key consideration when making career choices.
Adjusting to a 9-5 work routine after your PhD takes a bit of time. After one week into a new job, you may have clearer work boundaries, a better work-life balance, more thinking space and more social interactions.
