A few years ago, I was cycling to work and I came off my bike and fell in the road.
Got to work and my supervisor asked if I was OK, as I had “come off my bike”
I asked her how she knew….
One of the directors (the guy who had actually hired me), had driven past and seen the whole thing, and told her……
But did not even slow down to make sure I was OK.
They would watch you die in the road and not give a crap.
Make sure you do as little as possible at work and take any paid sick time off you can.
