Posted By Sean Fraser Kevin, No-one seems to be taking this one up, so what I would suggest from a safety point of view is getting the HSE booklet "Officewise", available on their website on: http://www.hse.gov.uk/pubns/officdex.htm If you are talking about general conduct then you are into the realms of HR - the company determines the rules, as long as they are reasonable, and add these to new contracts (contract re-negotiation is a tricky subject!). If you have union representation then they need consulted, if you don't then it is good practice to consult the workforce generally anyway. Once it is in the employment contract it can be enforced - if it isn't, then it can't (seems obvious but there you are). The problems that arise in these things are all different, but be clear on what it is you want to achieve, the justification for it, listen to concerns and address them with understanding and tolerance and be prepared to negotiate. Good luck!
