The warning came in the form of a release to the media yesterday.
The department said several security firms are not adhering to provisions of the Labour Code, including section C32 which mandates that wages be paid on a regular periodic basis.
Firms, the department said,which continue to breach the law regarding payment of employees will be prosecuted without further notice and the names of the principals of those delinquent companies will be released to the public at a later date.
Acting Labour Commissioner Eltonia Rojas said the “stern and decisive” action comes after repeated warning to companies.
The first notice to security companies was issued back in January 2015.
