When they built the building, more employees than cubicles. Her group was given the option of working from home 1, 2, or 3 days/week . . . my Wife was working from home 2 days/week ever since they moved there. Her managers got reports on work stats daily. When she was on short term disability after back surgery last year she logged on and did some work . . . her direct supervisor called or sent Email (I forgot which) and told her to stop working! So they know who is doing what. Her direct supervisor tried convincing the upper manager to allow her to work full-time from home but no dice (prior upper manager retired last December, she would have allowed it).
