"really like? cause your workers are liars?" is not an ad hominem attack, it's contradicting you by pointing to evidence. Eyewitness testimony, by your workers contradicting you, is evidence.
In this case, compare the thread to a normal conversation. A normal conversation consists of a long chain of alternating messages by two people, comparing and contrasting their two different points of view.

Compare that conversation to the first 1 minute of this clip: https://youtu.be/ZsBz_Q62hHk?t=10
