im a trade tested plumber.

i have sent my complete CV to a few BEE construction companies that regularly get awarded big tenders by govt, municipalities etc

i was told that i just need to be on site daily- the actual work is done by other non qualified plumbers contracted to these companies

maybe im paranoid but i suspect that my qualifications can easily be printed out and submitted- making it look like im part of the project
and the company avoids having to pay me while giving the impression that they do have a qualified plumber on site.

can this happen?
is there any way for me to check if its happened?

obviously without going directly to these companies as they will deny it & i will have no way to prove my suspicions.
