I wholeheartedly agree, RainyDay, it is most concerning that this employer is 'organising complaints' against an employee. Notwithstanding the fact that this behaviour it is illegal (and will have serious consequences for this employer if it is discovered), it is a cruel, shabby, disrespectful way to treat any human being.
In my view, the options this employer has in terms of dealing with this employee are:
1. formally meet with this employee and set out the 'people difficulties' that are so detrimental to the organisation. Allow the employee to respond. An open discussion could be a surprise to the employer. The root of the 'people difficulties' could be lack of motivation or boredom at work, domestic unhappiness, concerns about retirement, financial worries, or a range of other issues that could actually be resolved. In fact, just one meeting could allow both sides to see the other's view and both could then take steps to remedy, follow-up and review, etc.
2. if the employer is determined this person should go, then they will have to look at whether they are entitled to dismiss this person. There is scope in instances of gross misconduct, persistent sick leave, and in other circumstances where an employer may terminate a contract of employment. The employer should seek legal advice on the matter - but it would seem that this employer won't even consider this.
3. redundancy situations arise where the job is gone, and there is no alternative work matching the employee's skills. You might be interested to know, that many employees in Ireland each year take 'early retirement'. This is often in fact 'redundancy' situations. Would the employer not consider this option instead - that is 'offering an early retirement' package to this individual? Again - the redundancy situation must be genuine otherwise the employee could seek redress. I might have more information on this early retirement issue so if you PM me, I will forward this on to you.
I might also suggest to this employer, that since they are engaging in 'orchestrating complaint's' against this employee, they should be aware the employee has the right to view this information and could in fact challenge these 'complaints' through the courts.
On a final note, I think this is a sad reflection on this employer that following 30+ years service, they are subjecting an employee (any employee) to such poor treatment rather than managing the problem. Everyone in Ireland is entitled to fair procedure and the decision to 'organise complaints' is in direct contravention to this.
I feel very sorry for this employee. Irrepective of 'people difficulties' nobody deserves to be treated like this. Consider carefully how you will proceed and be aware the course of action you are advocating is against the law.
I am sure many people would be interested to hear how this turns out so perhaps you might post again here and let us know what happens.
