What if you were assigned PM of a project where at certain point you were re-assigned at a lower level by the PMT? per labor law what is this?

As per the Jordanian law:

The employee shall have the right to leave work with no 

notification while keeping his/her legal rights related to the end of service 

and the arising compensations of damages in any of the following cases: 

A. Employing him/her in a work that is significantly 

different from the agreed upon work in accordance with 

the work contract provided that the provisions of article 

(17) shall be taken into consideration. 

Article17: 

 The employee is not obliged to undertake a work that is 

significantly different from the agreed upon work in the work contract 

unless the necessity so requires to prevent the occurrence of an accident, 

repair what has resulted from such accident, or in case of force majeure 

and in other cases stipulated by law provided that this shall be within the 

employee's capability and within the limits of the condition that has 

entailed that work. 

I think its internal rules for company, as per contract between employee and company.
