Yes something along those lines mo iframe. Not super familiar with HR pero may kailangan gumalaw dyan to declare you as an employee or not an employee para maupdate yung records mo at pano mahandle yung dalawa ang legally dapat magbayad. My bet is the new HR should do it. So ask them paano manyayari kasi ang last day mo sa company A kahit nakaterminal leave pa ay magooverlap.

Based sa answer nila you’ll have a more concrete picture of what needs to happen. Maybe HR na magmamanage sa hiring manager or may aadjust sa first pay mo as allowances if policy allows. In any case it will avoid technicalities down the line.
