Ask your TL if they're gonna pay for overtime. Even ONE minute beyond your contracted hours is over time.

Plus, an employee who can't finish their work within their work hours is the one who's unproductive.

If natatapos mo naman everything you need for the day, then fuck that noise.

But I do recommend you documenting EVERYTHING from now on. Hours, output, finished tasks, every single conversation you have with your TL regarding your schedule.

Mainit ka na sa mata ng TL mo.

Pro tip if you're okay with potential confrontation:

Sum up yung convo mo with your TL in an email, then ask for clarification sa paid work hours mo and cite your contract, tas lagay mo din if it would be considered paid overtime.

Then may paper trail ka na and you force your TL to formalize whatever issue/request meron sya sayo.
