Kat - there was a time when this sort of job posting was permitted on these Forums. As Roundtuit the rules changed and your posted is liable to be moderated.

But, even if your posting was still permitted, the way you have drafted it is not indicative of any intention to help the successful applicant develop their understanding of workplace health and safety issues.

If all you want is an admin assistant with techy skills there are probably better places than these Forums for finding such a person.
