Purdue University announced Monday that it was backing down on planned changes in the policies about paid time off. The university proposed a system that it said would be more straightforward than the current system, but employees counted the days and found that their possible paid time off would shrink. On Friday, hundreds packed a meeting to express frustrations over the plan. On Monday, the university sent a letter to employees saying that the planned changes would be put on a "pause." While changes haven't been determined, the letter said that in revised plans, "the number of allotted days will be increased."
