To answer that question, you would need to take another look around you. You would also need to consider the professions and the designated job tasks of your workers. Ultimately, as a business owner or office manager, after giving this important question due consideration, you will probably be placing an early order for a new set of l shaped office desks. Also on your inventory wish list will be matching chairs that are wholly ergonomically sound. This test has been carried out numerous times already. The office worker that is cramped for space and entirely uncomfortable in his desk chair, so much so that his back aches, is not going to be very productive.
Taking the well-advised clean break from the desk every other twenty minutes is futile to this poor worker because no sooner does he return to his desk that the problems persist. But give him and his co-workers a new l shaped desk and a matching and ergonomically sound chair to sit in and see how quickly production picks up. The worker is comfortable because he also has more space to work in. He is secure in his role and works efficiently because he now has more than enough room to place all his work paraphernalia, all within easy reach.
The installation of l shaped desks also opens up the possibility of creating even more space on the office floor. Now that this space is cleared, it does not go to waste. Installing greenery and a strategically placed pause area still leaves plenty of room. If the office is quite small, then of course, a little inventiveness will be required, all in the interest of catering for the welfare of the worker and ensuring that production is maximized.
