Dennis McCutcheon supervises the employees who work in the building supplies department of a large discount hardware store. One of his employees, Kelly Sims, has been late to work every Tuesday and Thursday for the last three weeks. Sometimes she disappears for more than an hour at lunch. Although Sims had a positive attitude when she started the job, recently McCutcheon has overheard her complaining to co-workers and being less than friendly to customers. Using the questions listed in the section “Problems Requiring Special Action,” how might he uncover the true source of Sim’s performance problem?
