I unfortunately learnt the bitter lesson of helping my colleague with the basics of everything, which she took the credit for, and since I didn't have a close relationship with our manager, it appeared that she was fantastic at her job where I fell behind for simply helping her with the baby steps. It's a shame since I was so young at the time I'd have spoken up about it otherwise.
Also found that the way women were treated here was a little sub-par, the clothing allowance and being forced to wear heels in the offices is more than outdated in this day and age...
