I've been with my company for more than four months. A few days ago they presented us with a new contract which is very much different to the one we previously signed. Thing is, medyo pilitan yun pagpapasign kasi di nila kami binigyan ng chance to review everything and the HR was like 'Ito lang nabago dyan pirmahan nyo na' which as it turns out, is not the case at all. But me and my colleagues had signed it already when we get to see the whole thing.
Also, the contract was not stating that it is actually an amended one and is still dated 5 months ago, around the time when the original contract was presented. I would like to know if changing the contract midway is legal, and if it is not stated that it is the amended contract does it not void the original contract?
TIA sa sasagot.
