They (and I) understand that fulfillment workload is still pretty heavy (especially in OPU-focused stores since there's no way to equally distribute orders), but the problem is rather than make sure fulfillment is properly staffed to handle it on most days and then have those TMs help out in other areas when it isn't, they want to cut fulfillment and instead increase staffing for GM and integrate flex into the existing workload.
Except GM can't complete the existing workload and the increase in staffing doesn't mean anything under Jan - Feb payroll.. which probably won't get any better until Q3. At my store, the originally allocated hours in March of last year were just as bad as they were in January. COVID-19 is the only reason most stores saw a massive increase in hours (and overtime) during that time, and that won't be the case this year.
