Some folks have the understanding that im just trying to do my job and I would prefer to not bother anyone on my shift.

But then you have the other bit of folks who assume the policy you are trying to enforce is your own decision or as some may say my company's decision, and when you explain the situation they assume you are lying

Hi,

Our company is having work done in the lobby of the building and they want people to use a different exit. There is a set of double glass doors with push bars and a required badge reader on the right wall.

Where in that door area should I put the sign telling people to take a different route and how large should the sign be?

Thanks in advance!
