It really depends on the job. My 9-5 is hybrid, so 3 days in a week minimum, others can be remote. We have core hours, 10-4, where I should be available. So I can WFH and have something for 4PM, get back, and wrap up my last hour. But my boss is also very understanding, and if I need to be unavailable within core hours, he won’t force me to take PTO if I make up those hours.
