If anything we have a "please use your PTO" culture. I can't tell you the amount of times my manager, team members, and team lead have said, "Please take off time. Get off Slack. Disconnect."
My team was cut down to 5 people in March when we started WFH across the org, I hadn't taken a day off since October of last year. Our boss went to each one of us in the past 2 weeks and demanded we take time off.
While it's a nice gesture, it's the sign that even management knows they have worked their people too much. It sucks when you are on a small team that handles so many applications/systems, you feel guilty when taking days off.
Sure, I'm only gone for 2 days, but my team was even more shorthanded than normal for those 2 days and everyone had more work because of it.
