You are a chemist and u still ask these type of question?

too much reactions until cannot do maths? JUST LEAVE and here is why:

1) singapore does not reward technical skills, so managerial work is the way to go
2) Fixed remuneration, meaning there is no hijack of pb or any other crap.
3) you will need that 7extra leave when you get older.

Notice I didnt add that higher pay? because that is just a bonus!
