A: I have not encountered your problem, but am intrigued by your predicament. I would like to see your advert, if it bluntly said, ‘Young Apprentice Wanted’ or ‘Over 50s need not apply’ I could see your applicant had something to complain about. But if it simply contained a phase like, ‘Physical Work Involved’ then I suspect you are facing a gold-digger.
To find out, suggest a meeting. He or she will probably refuse but it is worth a try. Face-to-face you may well sort things out and will certainly learn more about the grounds for complaint. Sadly, if you end up in a tribunal you will need legal advice. Employment law is more about being a good box-ticker than a good boss.
If you lose this case it will probably be on a technicality, so be prepared to put all your paperwork on display.
Stay calm. There is no point in getting irritated even if this complainant is mischievous. If you pay him any damages you will do so with a clear conscience and a certain sense of injustice. Read John Timpson’s agony uncle columns on the Telegraph website.
