> No one is saying you can't be critical of your own employer. They are saying there are repercussions to being critical and loss of employment is a common one which should be expected.
Why do you feel that the expected outcome of being critical is being punished instead of addressing the root causes of these issues? I mean how do you expect problems to be pointed out and addressed?
Most companies I have worked for have a means to point out problems in an internal non-public manner. Once you bypass those to go public you generally lose the trust of your employer. Why would you employ someone you can no longer trust?
