Haven't Been Paid In Over 4 Weeks Since Starting Period.

Sorry if wrong flair not sure what to use here.

Location: Texas.

Since starting a new job on the 10th of last month I have been promised a few different possible pay days from both my direct supervisor and the person above in writing. Since that period I still haven't been paid and when attempting to be provided the number or a means of contact for hr I was denied. I also know full well that other employees have been paid within the most recent pay period and again have proof in writing from another employee that they did come by to pick up their check and was there to see them receive it when transitioning shifts.

I understand I can file a wage claim but I need this paycheck now. I am hoping to simply not show up to work until I receive my pay as withholding labor but I don't know if there's any possible defenses I can use to prevent a possible firing in the case I do it and I understand that Texas doesn't have any strong workers protections.

Can my boss legally fire me with all this if I don't show up until paid? What can I tell them before filing a wage claim with the Texas labor commission as I do believe I would receive faster and more immediate results with the right wording? And what should I do to protect myself legally?

I work as security but the company I work for is contracted to another. Im essentially a gate guard for a truck lot and my direct supervisor has messaged me to confirm the owners of said lot are supposed to be responsible for my pay.

For now I have
