And how long will the cooks and servers then be saying "Look, I'm doing these extra duties outside of my original job. I need to be compensated more."?
You see? They are not going to escape the labor/wage issue or disgruntled employees in either situation. If you hire a dishwasher at higher than some of your older staff, then you have a problem. If you have people filling in on that job from time to time and expect them to also do their regular jobs, then you have an issue. Oh, and not to mention, if you have people splitting duties or adding more to their plates, don't you think their performance in their regular position will suffer? Tables may have longer wait times because dishes are not available or either a cook or a server has to get the dishes caught up... That dishwasher has a direct impact on the total operation of the business.
Again, I'm not saying this is an easy decision for an employer to make, nor am I denying that the govt played a major role in creating the problem. All I'm saying is that we are here now. So how are you going to fix the problem?
@DonjoVol suggested paying slightly more to attract more lower skilled workers and inadvertently lit a fuse.
