There seems to be a flood of "Not an answer" flags on answers on this post. Many of the answers so flagged were, in fact, trying to answer the question. If they're low quality, downvote instead please.
The fundamental issue on the post in question is that the asker is clearly asking, "How do I make my team more punctual?" while many of the answers say, "This is why you shouldn't make the team more punctual."
Are these sorts of answers appropriate?
Here is one (slightly abridged) example with +18 score:
It's possible to convince them to take it, but you'll need good arguments and there almost certainly will be lingering resentment about it. You may or may not lose good people over this.
From your description the main reason appears to be jealousy from other departments. Have you considered giving the other departments the same perk?
In short: Don't do it unless you think it's worth losing some of them over it.
The answer says it is possible, but doesn't explain how. It suggests making other teams less punctual rather than fixing the problem that the asker wants solved. It says not to do it because you may lose people when the asker clearly stated "I have the full support and backing of the senior management team and am empowered to employ whatever devices I feel appropriate to get this taken care of."
Is this an appropriate answer to the question?
