I work in a tech-field and for most jobs I’ve been on there’s been core business hours that you’re expected to be in your office which gives all the workers a little bit of flexibility. Core business hours are usually around 10am to 1pm. How it works is you do your 8 hours however you want, so long as the building is open, and you are in the office during core hours. We have a good-sized early morning group, also a smaller group (usually younger) that comes in later in the morning and hang out til 6 and then go out for drinks afterwards. Most of the jobs also allow people to flex their hours within reason. So you can work a 8+ hour day to work a shorter day later.
This little bit of flexibility is so great - allows parents more time with their kids, going to appointments, avoiding traffic, etc. Literally saves you so much in PTO and $$, as well as other residual benefits to your health and wellbeing.
EDIT - For clarity, they usually don’t show semi-flexible/flexible work schedules in job postings, but definitely ask during interviews. Let’s be real, a 4-day, 8-hour/day schedule won’t manifest in this lifetime, so this and WFH are the next best things.
