Been doing this a long time...
I'm a 3rd generation sign maker, starting way back when all we had were brushes and paint... Things have come a long way to the point where we have a shop which employees 32 people... We have 3 dedicated applicators (vehicle wrapping, digital and vinyl lettering application)... Having done the work myself I feel that standing is by far the more productive method, especially when it comes to weeding really large panels. But having said that I think each task is unique and the employee doing the task should be able to exercise common sense and determine which method (sitting or standing) is the more productive method. Then again I have had staff that love to lay on the job, elbows on the table, the works... I have a problem with that because I can very quickly get my head applicator and within a very short space of time prove which method is the more productive one. Admittedly there are days folks are not on top form but I would prefer that not to be the norm. End of the day let's get on with the job at hand, I'm not into dealing with lazy staff with a million reasons why they cannot be more productive... It always amazes me how the laziest folk have the most amazing excuses. I trust my staff to make the right call, I do not agree that chairs/stools/etc. should be removed from the workplace.
