Dist. Ct. did not err in granting defendant-employer’s motion for summary judgment in Title VII action alleging that defendant terminated plaintiff from his position on account of his Chinese race and in retaliation for complaining about workplace issues. Record showed that plaintiff was terminated because he consistently refused to accept weekend work as other members of his team were required to do. Ct. rejected plaintiff’s argument that defendant could not require him to do weekend work, where said requirement was not in original job description, and plaintiff’s offer to do Sunday work did not require different result, where others were required to work both weekend days. Moreover, summary judgment was appropriate on retaliation claim, where subject matter of plaintiff’s protests did not pertain to unlawful discrimination.
