'Blacklisting' someone is illegal.
However, depending on the reason you were dismissed, when the people in Human Resources call the references on your resume - CV- the people who let you go could be telling them things that actually happened, but you do not want the new boss to find out.
So, If you were dismissed because they were closing a department or business was slow...that is not a red flag...but if you were dismissed because a supervisor observed that you did not do your work, or were constantly late, or that other employees complained about you...and that person is where your references are directed...they are telling the people who call..exactly why you were let go.
It may be a good move to call that person and tell them that you are desperately looking for work, and that every time they say something bad about you, they prevent you from being hired. Send them a $10 gift card for something.
FINALLY the recruiters......
:::SIGH:::
The recruitment agencies are just that. They are looking for 'warm bodies' that have 'qualifications' that match one or more qualifications of a business that is hiring. The recruiters are generally 3rd parties who scan the want ads for companies that are hiring and then scan Monster, Indeed, Craig's List and other places where people post resumes for resumes of people whose qualifications somewhat match jobs.
The call you in and they interview you and they tell you how great you are, how wonderful your qualifications are and how they have several jobs that are JUST PERFECT for you. And then they never call back.
Why?
Because on the other end there are companies like mine. We need people - so we advertise on Monster, Indeed and other places. We also scan those websites for resumes of people who EXACTLY match the qualifications advertised. We call those people in and interview them and probably hire one or two.
In the mean time, after I have put up the ad and while I am interviewing people, the recruiter is reading the ads, and contacting you.
99.9% of the time, by the time a recruiter sees the ad, calls us and makes their spiel and gets us to agree to pay them a fee for referring a good candidate...we have already hired someone. And if we have not, unless the recruiter is VERY VERY good at what they are doing... the people they are referring ...those people seldom have more then 3 of the qualifications we are looking for.
In all honesty...in the past 5 years we have hired.....about 150 people....and only 2 of those people came to us through a recruiter.
You would serve yourself better if YOU were the one contacting potential employers and just forget about going through recruiters. IMHO...they are hurting your chances more than helping them...unless you are in a VERY SPECIALIZED, HIGH SECURITY FIELD.
