Always be vague. Say I think they’re in today or not until later. If they press say it’s company policy not to give out the schedule. Most companies do have this and even if they don’t how would a stranger know. Don’t give out specifics, they can get people injured or even killed.
At my last job someone came up and asked when “Sarah” was working next. I didn’t tell him and then texted her a description, turns out he was an abusive ex who had been stalking her. Don’t do this shit please.
One time someone called where I work looking for someone. The person who answered the phone said she was at a conference. The caller proceeded to drive nearly two hours to the city the conference was in and buy a day pass to talk to the person they were looking for.
Do not underestimate the lengths people will go to to violate other people’s privacy if they think they can get something out of it. Do not make it easy for people like that.
