They'd be fine with it, and I have used this in the past, although yesterday I didn't have any on me. The stress got so bad I just left to go home early. It wasn't just the workplace, it was being late on two deadlines that also had me upset. But I find people will still interrupt you with headphones, and I can still hear the background noise, and still be distracted by people moving around. So it's a improvement but not a fix.
