If a long serving employee has made several mistakes, that are quite out of character, before dismissing them, you need to consider if they can be moved to another job. For example, a client contacted me recently regarding an employee (who has worked there for 15 years) that was misplacing money. The employee checks all the businesses finances, had built up a great relationship with other members of staff but was having a tough time personally. I would recommend that if a mistake happens, and you have noticed it, keep an eye on the staff member. The first time is almost always an accident, something outside of work may have affected them, but that accident can lead to a habit and a habit can turn into fraud.
So, keep an eye on them to ensure that they do not make the same mistake again but also to see if they are alright. The mistake could be due to their own fear of making the error, the pressure from home life as well as work can possibly be too much. Unfortunately, the error concerned quite a large sum of money. The staff member could not be moved to another department and the management had lost trust. The employee realised that they would be dismissed and instead handed in their resignation to not go through the exit process.
When it comes to business finance it’s always a good idea to have a second pair of eyes on what is happening, so you can catch mistakes early before they become a habit and then fraud. The saddest part of all of this is that I have never come across a situation where the amount of money taken has been large enough to pay for losing your job, even if the person deliberately set out to steal from the employer.
