While a doctor's note recommending limited working hours may indicate a "need" for leave, it does not indicate the "reason" for leave. See Lawson-Brewster v. River Valley Sch. Dist., No. 06-58, 2008 U.S. Dist. LEXIS 33060, at *5 (W.D. Mich. 2008) (holding that a doctor's note advising plaintiff to remain off work for four days did not constitute sufficient notice of plaintiff's depression).
