Management can convey to the floor personnel that the current procedure is not cost effective, nor practical. This can be done with a informational literature release followed by specific training, a meeting, or both, depending on the level of familiarity the employees have with the new process. Information on the high costs the company is incurring as well as the problems that can be caused by using the present method can also be brought into the mix as well. They can then choose to embrace the much more cost & job effective method as well as the NEW company mandated procedure to use gas lenses, or Management can start the disciplinary process on the holdouts. Crack the whip once, maybe twice & everyone will get on board...Union or not.
I'm not trying to be smart, or say being a thoughtless tyrant is going to produce results, it will not. But common sense goes a long way when making a point about a current procedure that is clearly wasting the company's money as well as not producing the best possible results. I was an asst exec supervisor running a large kitchen crew for over seven years in Las Vegas. When a procedure is currently being used out of a "traditional" process, but is very wasteful & or unnecessary to the job pertaining, Management has a responsibility to the company to correct the issue. Especially being, there is a much more cost effective & efficient method available. Engineering should not have to conduct a floor demonstration to get the point across. Simply present the facts, provide the necessary training and a reasonable period of time for adjustment to the new process. Then, they can either choose to get with the program.....Or get down the road.
My thoughts, for what it's worth. S.W.
