This is a little easier than explaining to your boss why you are 10
minutes late. You can think of an excuse ahead of time, or tell them
about an appointment so you can leave early. You can use the same
excuses as the ones I mentioned earlier. You just have to change the
wording a little and make it future tense.
"I have to leave a little early today. Is it ok if I finish my work at home?"
"I have a dentist appointment at four. I have to leave early today."
"I have a dentist appointment tomorrow at four. Is it ok if I leave early tomorrow?"
"I have to pick up my wife at the airport tomorrow. Is it ok if I leave at three?"
"I have a conference with my son’s teacher tomorrow at three thirty. I have to leave at three. Will that be ok?"
"I have a terrible headache. Is it ok if I leave early today?"
"I think I might be coming down with the flu. I should get some rest and try to fight this thing off early. May I leave early today?"
"I’m not feeling well. I think I should get some rest. Will it be ok if I go home early today?"
"My son got sick and I have to pick him up from school. Will that be ok?"
