I was just wondering what is too late to call a teacher on a school night? As a sub I get calls @ night to sub. Since I am in school 2 nights a week until 9:30 sometimes 10pm I might not get the call until then. I have gotten the call @ 10pm before and did not want to call back for fear of waking up the family. Some of the teachers (and I know it for a fact) have kids from birth-3yrs old also some are school age and I do not want to wake them. If you call a sub @ night is there a time limit. Like example, if they have not called you back by x time you give up on them?
