Wow, you are trying so hard to discredit the posters on this site for a person who has no allegiance to ADP. Perhaps you are the one being paid by ADP to try to salvage its reputation.
But no matter. While this layoff site also has less than 1% participating it allows people to express their views more openly. It is a "blank slate" that allows people to write what they want. So since the people here are not limited to preset questions, the fact that so many posters agree in this more open discussion means that the representable sample can be less in determining what people truly believe about ADP.
The number of views for each post is also reported openly here. Most of the views exceed the less than 300 from comparably.com. So arguably the number of people who see these posts and have an opportunity to comment here far exceed the number of people who answered on comparably. Thus, the representable sample is quite a bit bigger than comparably.
In addition, as several posters have commented here, ADP tries to fudge the numbers of the outside companies that conduct these official surveys. On this site, you can't fudge stuff because you have intellectual "blank slate" discussions where views can be challenged by others.
And who said anything about doubting the scores of the other companies and winners? This thread is about ADP, not other companies. I and many others here don't know about those companies and are not qualified to speak about them. I simply don't know and will not offer any views on those companies.
And about the competitors that beat out ADP, I also don't know about those companies. I don't know whether those scores are invalid. However, as you believe that the comparably.com ADP scores are valid, then you will have to accept that the competitor's scores are also valid. How then do you explain why the competitors beat out ADP? Perhaps you will say that ADP's score was valid, but the competitor's were not? Try not to trip over your words answering that one.
