Hi. I graduated my engineering degree back in 2016. I got a job as a Corrosion Engineer in mid Jan 2017. My company sponsored my EP and my fixed salary is S$2,200. Recently I've just realised that the minimum salary for EP holder is S$3,600. Am I being cheated by my employer? I don't want my EP to be downgraded to SP, and of course I wanna get the minimum wage. What should I do now?
