I absolutely agreeAs someone who has provided input on what is "youthful folly" from criminal conduct when employing people in the NHS I can clearly say that a conviction for burglary is too serious to ever be discounted.
Getting caught stealing sweets as a fourteen year old and receiving a police caution or possession of a small amount of drugs for personal use as a seventeen year old may be not be a bar to employment in the NHS but sufficient time will needed to have passed to demonstrate no further criminal conduct and significantly greater maturity.
Those who have access to patients, patient records, drugs and mortuaries should require an enhanced DBS check, which is out of date the minute after it is checked!
What does not happen is that anyone with employment requiring criminal record checks should be on a national database so that the employer is automatically informed if they are arrested or come to police notice where there is concern of risk.

I was just scratching my head - why was he allowed to continue working there????
