Had a day booked off on Friday as holiday as was going away for the weekend. Ended up not well yesterday and phoned in sick. Went back today and my (female) boss made my whole day a misery. She is clearly not happy that I was off yesterday and resorted to picking holes in everything I did today and talking over my head. Should I a) ask for a meeting with her or b) go above her head or c) just leave? I find it totally pathetic and childish, she clearly does not believe it was a genuine sick day and is determined to make me pay for daring to take a day off. Advise please?
