There are loads of jobs available, but an employer can pick and choose who he or she employs.
If they can't fill an application form in legibly, have a bad attitude at the interview, they haven't a hope in hell.
Throw in a conviction for theft, sexual offences or other unsavoury behaviour, not a hope.
Yes, I know there are lots of 'bad turned good' people out there, who have crawled out the pits of hell to lead a good, productive and wholesome life and everyone deserves a chance...
