Oooooops. I would offer you advice, but considering your problem is of your own making I think you should find your own solution.
oh dear lol not good. can you use your last illness as an excuse. was you out with any of your work mates last night? if not maybe say you had to go to emergancy dentist. or be honest and say you slept in late if it doesn t happen often i m sure they ll see its just a one off, so maybe honesty is the best policy here. at least you have gone into work. good luck
Go to a doctor tell them you were off for a week and you still feel a bit ill. A doctors letter will cover you in case they try to take any action
Don t listen to these dumb people on here everyone makes mistakes. Look just tell your boss you still felt a Little ill and you waited for a little to see if you would feel better.
In this economy no offense but your an idiot , get off the computer call your boss and get to work. they can replace you in a minute. grow up dont get wrecked on work days-god how stupid are you
