Trying to get some more news on this as it doesn’t seem to be gazetted yet.
From Phuket gazzete
on 27 March 2018, the Emergency Decree on Non-Thais’ Working Management (No.2) (2018) (“Decree No. 2”) was issued. Decree No. 2 amended Decree No. 1.
Section 70 of Decree No. 1 (and the Act) provided that “a person who is granted permission for working may not carry out the work of the type, with the employer, in a locality or on any working condition that is different from that specified in their work permit unless permission under Section 71 is obtained.”
Section 71 of Decree No. 1 (and the Act) provided that “a person who is granted permission for working, and who intends to change or add the following particulars, must obtain permission from the Registrar: (1) type of work (2) employer (3) location or (4) working conditions.”
And Section 73 of Decree No. 1 (and the Act) provided that “no person may allow a foreigner to work in a manner different from the requirements specified in the work permit.”
However, and very significantly, Section 37 of Decree No. 2 repealed Sections 70, 71, and 73 of Decree No. 1.
Furthermore, Section 28 of Decree No. 2 provides that a work permit holder may engage in any work that is not specifically prohibited to all foreigners on the “Official List” of work prohibited to foreigners.
