Just how it should have happened.
A phlebotomist had her office decked out in patriotic regalia. There was a management shakeup, and the new management wanted all the offices to look a certain way. So she quit.
LabCorp of America had every right to tell her how her office must look. She had every right to articulate the conditions under which she'd work.
This isn't about "patriotism" or lack of same, but about workplace micromanagement. I hope they lose a few more valued employees.
