Not usually. I once worked standard hours across 4 days. And even though it’s the same amount and the standard work day is longer. Gaining a full day to do whatever is so much better. The work day is usually only increased by 1-2 hours with one of them days being slightly shorter than the others too. Less time commuting (if you’re in office) is a benefit too. I wish my current company could go 4 days, but it’s unlikely to happen due to our clients.
