BREAKING: SCOTUS Grants Cert. in Employment Discrimination Timing Case

A few minutes ago, the Supreme Court granted certiorari in Green v. Donahoe (order here | SCOTUSblog case page here). The issue actually seems pretty straightforward. Per the Petition for Writ:

Under federal employment discrimination law, does the filing period for a constructive discharge claim begin to run when an employee resigns, as five circuits have held, or at the time of an employer’s last allegedly discriminatory act giving rise to the resignation, as three other circuits have held?

Sounds like an interesting issue, that should have a bright line rule.
