And sometimes those recommendations get implemented in awful ways in public buildings. And that’s why my office will be hot and humid when I get to work on Monday–the A/C gets turned off over the weekend and it takes forever to catch up on Monday. Never mind that I work in a library and books do not deal well with changing temperature and (especially) high humidity.
Could also be job postings to convince current workers that their overwork will soon end because the company is about to hire new folks. I’ve seen that theory floated to explain the “help wanted” signs at fast food places that never come down.
