if your a good worker you have nothing to worry about, I don't know your position but I'm happy for a prospective employer to get references, I've often not got a job because I was not qualified although adaptable and hard working but they would never beleive me. then i went to work for a comoany through an agency as a temp and they got rid of me when there were redundancies but apparantly the works manager was on the phone begging the agency to get hold of me when they needed a QC inspector (something I am not qualified for although seem to have an aptitude for and I'm learning fast). OK in this case it was because the company already knew me but they would have certainly highly recomended me to another employer had they been contacted
