For my company, the worst thing is that we have hot desks, which wouldn't be a problem if there were enough seats if, say, 90%-95% of all staff came in on the same day and had their own seat. However, one of the floors that my company leases out is undergoing renovations and they shifted all those employees to other floors while keeping the same in-office weekly requirements. Way too many times, I've went into the office just to not be able to find a seat. We have a hoteling reservation system, but even if you reserve a seat, if you don't come in by 8:50 or so, someone will have taken it. I've complained to our corporate services team and have never received a response.
