I'm an electrician and I replaced a bathroom vent fan in a small commercial space. The fan pulls air up from the room now, but when I was changing it, I noticed a draft coming in from the damper. Not enough to open the damper, but I felt it when I opened the damper and put my hand in. I looked above the bathroom (but didn't actually touch the duct) and it appears to be connected and going up to the roof. Is this normal to have a slight draft through the duct or should I tell them to contact maintenance?

(I am an electrician, not a DIYer) I have only ever replaced the whole bathroom fan unit. Client has a housing already in that measures 8.5 x 8.5 and new guts (different brand) that measure 8 x 8.25. old fan was 100cfm, new is 80cfm. What considerations do I need to make if I go with just replacing the guts? Should I just replace the whole thing? Normally I would, but there is no ceiling access. I could get a roomside fan if needed, but wanted to try to level up my skills by trying something different and this seems like a good opportunity.

I can't believe I just got fired. I have never been fired from a job in my life.

Where are regular weekday group fitness classes that start at or after 7pm. Yoga, cardio, dance...anything? Everything I see is usually earlier, which doesn't work for my schedule.

I just want a simple ON-OFF headlamp that is at least 800 lumens. I don't want to select through a red light setting, a strobe setting, a motion sensor setting, etc. Who is actually using these extra settings and why?
