A lot of these so-called Employment Agencies are rackets. They get money to find quality workers for companies, then turn away potential workers because they don't have a proven track record. It never occurs to them that 95% of workers with a proven track record are employed. It never occurs to them that the only way for some unemployed people to get a proven track record is ON THE JOB.
Covid-19 has been a convenient excuse for shitty people to be shitty.
