Yesterday I felt really unwell with a pounding head, just felt dreadful. It was meant to be my office day and I have a very long commute. I asked my boss with plenty of notice if I'd be able to work from home. The job doesn't require me to be in the office, I can do it on my laptop and I'm easily contactable throughout the day.
She is normally quite reasonable but she replied almost implying that I was taking advantage and that everybody would be doing the same if they could. I don't necessarily think that's true, some people prefer going into the office and feel isolated at home. She said that it should be classed as a sick day.
I ended up going in. I sort of see what she's saying but it's the first time I ever requested to work from home on an office day and I was still going to get the work done, there was no purpose for me to be in the office that day, I'm in a very junior role.
