If two good employees disappeared inexplicably, then Citrix is preparing for additional layoffs. This adds credibility to the rumours the 13th of March layoffs.
Some managers/directors likely receive MBOs to restructure their department by concocting pretexts to fire employees and thereby save Citrix severance costs. One such person is Barbara Geoghegan. She repeatedly defamed one of her reports and Citrix fired him, but he turned around and sued her personally along with Citrix. https://www.pacermonitor.com/public/case/22095533/Krieger_v_Geoghegan_et_al
Judging from the voluntary dismissal, Geogheghan’s actions must have cost Citrix some serious money. Citrix and Geoghegan picked a fight with the wrong guy.
