Had a fall

1st April - After two days of medical leave, the first thing I stepped into office. Something has happened to me. I had a fall in my office when I'm using the internal staircase, I have no idea how I fall. When I stand up and was accompanied by my colleague, Christina and Jeslyn. My tears was about to drop as I felt so pain. My leg was so pain. Just got a few scratches and slight bruises. Lucky didn't hit my head and my back.. My after awhile my back feels the pain so I decided to report to my HR but after sending the email, there's no reply from them. I'm wondering whether will they take any actions. Sigh... I hope they will do something to that staircase as the non-slip tape is wore out.
