Employment relations body the Advisory, Conciliation and Arbitration Service (Acas) has also suggested allowing employees to work flexibly during the event.
The guidance has called on businesses to plan now for the Games, which open in Glasgow on July 23, 2014, in a bid to reduce any impact from staff wanting to book leave or taking sick days to watch the event.
On the subject of dealing with "performance issues", the advice from Acas notes: "There may be problems around staff watching lengthy coverage via their computers. Why not plan for popular sporting events in advance - perhaps giving staff access to a TV during agreed times?"
One survey ahead of last year's Olympics reported that while one in six workers planned to take annual leave to watch, one in five were expecting to take a "sickie" to stay at home and watch the action.
In the wake of the Games, figures showed Scotland's council staff took 5000 fewer sick days while the Olympics were being staged, compared with the same period in 2011. However, some local authorities recorded an increase in sick days, including Aberdeen City, Glasgow, West Lothian and Angus.
A spokeswoman for the Conferation of British Industry (CBI) Scotland said: "The Commonwealth Games will provide excellent opportunities for Scottish businesses. However, companies need to make sure they plan ahead to deal with transport, logistical and flexible working challenges.
"For those aiming to attend or watch major sporting events, there is scope for them to use holiday entitlement or benefit from any flexible working arrangements.
"Employers are best advised to plan ahead accordingly, and communicate with staff about the available options."
An Acas spokesman said: "Big sporting occasions can present dilemmas for firms which might be worried about productivity or the after effects of lively celebrations. Employers need to start planning now to avoid problems later on."
