Start Date on Monday but still No Contract

Hi! Ask ko lang sana if anyone experienced this already.

My start date is on Monday (night shift), pero until now wala pa rin akong natatanggap na contract. I sent an email 2days ago, isesend daw nila 2–3 days before the start date, but hanggang ngayon wala pa. Medyo kinakabahan ako kasi malapit na weekend.

Wala rin akong details yet kung where exactly magrereport, ano mga need, or kung sino yung contact person for the first day.

Possible ba na hindi na matuloy yung offer? Imove yung start date? or Monday na mismo nila isend yung contract and other details?

Medyo worried lang din kasi wala pa akong nahahanap na apartment to rent. Ayoko mag-deposit agad if hindi pa 100% secured yung job, baka mamaya hindi pala matuloy yung offer.

Any similar experiences or advice? Thank you!
