Petticoat Junction - "Uncle Joe's Replacement" (1963)
When Kate and the girls go into town to pick up the pocket watch they ordered through Drucker's store - the watch being Uncle Joe's birthday present - Kate, in an effort to boost Herby's confidence, he who is working for Sam, inadvertently offers him a job as Assistant Manager at the hotel, with an imminent promotion to Manager. Herby readily accepts.
Kate doesn't have the heart not to give him the job, so she decides that she can give him some menial tasks at the hotel under the guise of the important sounding position. However, Uncle Joe believes that Herby's arrival and Kate not wanting him to go into town with her and the girls among other things means that Herby is his professional replacement at the hotel and Kate is setting him out to pasture against his will.
