People, particularly those in higher positions say, 'do what you speak and speak what you do'. But, we find many times in reality that only people speak and do not demonstrate. It is hypocrisy.
Audience, particularly those who are not from the same organization, feel and think great about the speaker by listening to the tall claims. But, insiders will have pessimism about talk by such leaders.
When some lower level employee speaks, nobody cares. But, when same of even lower level employee of some other organization speaks, people will be attentive and give respect. This leads to heart burn among the employees of the organization to which this leader belongs.
Sometimes, when talks are given by employees of same organization in which the show is conducted, higher level people go out to do their business, but this is not the case with talks from employees of other organizations. This leads to wrong impression among employees as participants that boss does not care about the speaker (and his work) and thus they too need not bother in future. This is particularly harmful to the organization when the speaker is from safety department. Similarly, questioning (or ragging) safety department employees in front of others for whatever reason it is, leads to wrong projection of importance to safety and this will only spoil safety culture.
