unsuitable by delaying in acting or allowing him to work his notice. A crime only counts if it means the employee is unsuitable for their work - personal dislike of particular crimes do not count. However, the employee could become unsuitable by virtue of being unable to perform thanks to colleagues not accepting his continued employment - the employer may need unsolicited complaints along this line. Even incest can be insufficient to justify dismissal. Dishonesty counts more if the job requires honesty, e.g. involves handling cash, third partys' goods, acting as security guard. For example, a shop worker who is caught shoplifting in another shop cannot be trusted. Hiding a conviction might be grounds, but the problem may be that the employer cannot obtain proof of conviction. Anything less than a prison term of 30 months eventually becomes "spent" after which an employer is not allowed to dismiss for it nor is the employee obliged to disclose. Tribunals may be dubious of dismissals of long serving employees with a clean HR record on grounds of some minor or irrelevant offence years ago. Imprisonment is not just a pretty good proof of guilt, but can frustrate the contract if for more than a few months, which would bring the contract to an end without the need for procedure or compensation. Being held on remand could justify a short spell of suspension on full pay, but if this is without pay or for too long (more than a few months) it creates a constructive dismissal. The employer may simply be able to say that a court has decided there was sufficient probability of guilt to lock him up and this informed its investigation, justifying dismissal. An employer can be entitled to dismiss multiple employees where it cannot prove who is guilty or to dismiss only some of those guilty based on blameworthiness. To dismiss several staff for incompetence because the employer does not know which one is the weakest will usually look arbitrary and could easily show lack of an adequate investigation. It could easily be fair though if safety is at risk meaning damage could be done that cannot be put right with money, for example, somebody forgot to bolt a jumbo jet's windscreen back in place and a pilot is sucked out mid-flight. Summary dismissal may be difficult to justify unless the employee appeared to have been guilty of a
