It might be emotional for some/most (mainly linked to the private situation of the employee?). But this doesn't mean it is irrational. There is either a clear reason for the fire or the problem lies with the employer. This basic premise is very rational. Some divorces and breakups might be like that, a lot of others not.

Tears will dry up. The reason/facts can help the employee a lot more than a short term comforting moment.

This doesn't mean I completely agree with the author, of course some empathy sounds like a good idea. But that's second to the facts.
