Williams didn't reply to the text, but the following Monday morning he raised it with his boss.
In response, Burkhart told Williams not to take it personally, to stop being a baby and to get back to work.
Member of the Authority Vicki Campbell found that "robust language" was part of their day-to-day dealings and common across the wider building industry.
Williams wasn't unjustifiably disadvantaged by the use of language by his boss, she said.
The following week, Williams and Burkhart were talking on the phone when Burkhart said it seemed that Williams wasn't happy in his job.
Burkhart said he should be looking for work elsewhere, and Williams agreed and said "sweet as".
Williams told the Authority he was acknowledging what Burkhart was saying, rather than agreeing with the offer to look for work elsewhere.
Williams said there was no opportunity for him to respond to Burkhart's concern about his performance.
Campbell found that there was not actual agreement from both parties that Williams was to end his employment and ordered Burkhart Building to pay Williams $5000 in remedies.
