ST. LOUIS - Although some union activities by telephone company workers who allege that they are owed unpaid overtime are not compensable for the purpose of calculating overtime, the question of whether grievance meetings and the workers' charitable work can be used to figure overtime raises genuine issues of material fact, a Missouri federal judge held Dec. 17 in granting in part and denying in part the phone company's motion for summary judgment (Josh Kayser, et al., v. Southwestern Bell Telephone Co., No. 4:10-cv-1495, E.D. Mo.; 2012 U.S. Dist. LEXIS 177990).
