Assuming since u ask this kinda question, i presume that your experiences is not that professional and your current work is nothing to beproud of.

In view of that presumption, you can try to fake ur payslip (altho im wondering what kinda technology you have to do a fake payslip).

Further, in your profession, i dun think u have a reputattion to spoilt to begin with. so why not try it out. let me know if u get thru,k??
Go for it!!!

and ur question "Isit ethical?". Tell me one situation lying about employment is ethical??
