That just sounds like a bad idea all around. This is Subject’s investigation and Subject’s or their supervisor’s can accommodate a normal reasonable hours work schedule if asked nicely. At one point in the past this request resulted in the Supervisor arranging for me to fly on a military plane to a remote military base to meet with a Subject. This job doesn’t pay enough or come with an option of real authority (ie a weapon) to do things like meet with strangers at midnight. Thinking we have to “do” things like that is part of the horrible high turnover that is difficult for all.
