Stephen While you write 'My question is, to what extent do we have to go regarding the ergonomic setup, you then curiously focus on simply a very small aspect of ergonomics. An adequate answer to your question requires reliable data on the range of tasks to be undertaken in the 'breakout' space, relevant body dimensions of a good sample of the users, their ages and details of any physical impairments which is apt to contribute to musculoskeletal or eye fatigue or other sources of stress. Any bona fide 'ergonomic' response would design a solution based on this data and includes relevant training and guidance for all employees involved, their line managers and senior management. Its scope should be far more than tabales and chairs (or possible sit/stand options for working) and should have regard for lighting, ventilation, heating and possible sources of stress. I regret if this is contrary to your notion of ergonomics; unfortunately, too many safety texts dwell on a version of ergonomics that is simply over 30 years out of date.
