For the low-skill stuff, treading dangerous ground. We had four part-time warehouse workers, each approx $11USD/hr.Did the mundane/grunt stuff. They were not poor employees, but they had no skills not easily replaceable, so managers gave little consideration to their joint demands for increased pay and benefits (not unreasonable requests). But the incremental difference of their demands did make it worthwhile for the boss man to block out several weeks of engineering time to automate. My employer now has ONE par-time warehouse worker.
And the result of this was essentially zero stocking error, and I learned pyQT.
