Facebook? The Couple? The Boss?

A couple recently lost their child to death. They were extremely devastated, consequentially; they needed a break from work for some time to get over the loss.

The wife pleaded with her boss to give her the break. It took a while for the boss to agree, but he finally did. He gave her a 4 week-break.

The husband also got a break from his work-place, and the couple decided to go to the BAHAMAS!    . They had a very good time.(understatement).

When they got back form the trip, they immediately uploaded the "BAHAMAS pictures" on an album on FACEBOOK and tagged "the whole world".

The wife got to her office to resume work on the Monday. She received a Sack letter instead. She was laid off.

The reason? The boss got to see the pictures on FACEBOOK and it obviously didn't sit well with him.

 "She was supposed to be mourning, instead she's drinking Margaritas and chilling by the beach." <<<<Though this was the REAL reason why the boss sacked her, that wasn't what was said in the sack letter---(the boss found a flimsy excuse to lay her off).

So my question is: Who is at fault for the conflict? --- Facebook? The Couple/the wife? The boss?
