Before pay salary every month, we're always busy, HR and finance department staff use our OA system to calculate all employees' salaries, the OA system is developed by our department, and I'm in charge of the time attendance and salary.
The girl, my colleague from the HR department, who is responsible for calculating salaries has not much experience of her job, sometimes would make mistakes, when this happens, she would get nervous and ask me for help, and I have to look up the code and locate where the problem is. Like today, it was time to leave, but she needed my help, so I had to stay in the office and work with her, but eventually she found her mistake. It was 19:00 when I left the office. And I can get an overtime application for 1.5 hours tomorrow.
A lucky day.
