Minister of Finance Colm Imbert and PSA president, Watson Duke, have agreed to draft a Memorandum of Understanding on the structure of the proposed Trinidad and Tobago Revenue Authority.
The decision came via a meeting of the ministry and the PSA on Wednesday.
Legislation on the authority is now before a Joint-Select Committee of Parliament and requires a special majority vote.
Minister Imbert said the two parties discussed issued of job security and employee benefits, as well as union representation, the health plan and pension plan.
The minister said he asked the PSA to put their requests in writing so that the ministry can have a clear indication of all the issues.
He said Duke, in response, requested that the MOU be drafted and settled, showing the shape and form that the Revenue Authority would take, and outlining the protection of workers.
Imbert said Duke gave an undertaking that within a month the ministry will get a document from the PSA identifying what their concerns are.
The ministry's permanent secretary will work with Duke on the drafting of the MOU.
Minister Imbert described the meeting as "very cordial" and said they made "a lot of progress".
