Its not just lowes. Many businesses are hiring more and more partimers at entry level and fewer and fewer full timers. Truth is, if you look at the rotations for each department there is no hours plan for full time CSAs. Stores were never suppose to have so many full timers to begin with, but managers over the years promote people to FT CSA without thinking about the big picture.
If every store ran on mostly PTs, then they would keep their 20 hours during slow seasons and pick up hours in the summer. Instead, stores are bloated with FT that the budget does not allow. They take up hours in the off season so store start out in the hole after feb. They take vacation for 2, 3 and even 4 weeks a year with no one to cover them because you cant flex up peoples hours if they are all FT already.
So yeah, blame managers that promoted people to FT without realizing what that would do long term. Now current managers need to undo the damage and look like bad guys in the short term. But if done right, this can actually help a store be staffed in the busy months and not cut so drastically in the slow months. And if people were smart they would manage their income based on the reality that those summer checks arent forever and maybe try stashing away a percentage of them for the winter.
Of course, if we had a better economy and less inflation then payroll budgets would increase with sales and this wouldnt be as big of a problem.
