I suspect one of my employees is stealing

[needtoask]

I am a regular with a name change.
Obviously I need proof.
Can I get a security camera installed.
Do I need to inform my staff that I intend to get a camera.
Anyone please help.
Thanks

Obviously don't tell them which customers have reported them!

Thanks everyone for the great advice.
I have decided to visit the police and CAB to have a one to one chat and ask them about the legalities.
I will be placing 2 camera's, one above the till and one facing down the shop premises.If I have to alert staff that a camera is being installed then so be it. I will do that.
I run a nail emporium and beauty business and I will also be keeping my eye on my stock. tbh I feel a fool as I have trusted this girl and left her at times on her own as I have nipped in and out.We do have an appointment system but we also get walk in clients for other services such as ear peircing and eyebrow waxing, mini facials etc I also have another member of staff who works alternate days, who has worked for me for years with no probs.

Taking aside can work if you have no proof. It could even force the employees hand into resigning (but be very careful that they do not claim constructive dismissal (not a problem if they have under a years service))the only problem that you may have is that if you show that you have proof and took no disciplinary action then if it happens again in the future you will not be able to give a warning or sack as you have set the precedent (ie you steal, we do nothing).

Obviously this is the worst case scenario, but I've seen many managers come unstuck by not following a proper procedure. It's very frustrating when you know that the employee is in the wrong but can make a valid claim at an employment tribunal.

Just wanted to add to BIWI's post. This can work, and does in fact happen. In one of my old shops, a thieving employee was grassed up to the boss by a loyal customer. I was most impressed.
