My boss gave me one month notice to quit the job...

if the work contract is limited the contract is terminated by the employer, then he is liable to compensate the worker for the loss he obtained as a result of the termination of the contract, provided that the amount of the compensation shall not exceed half a monthly wage for three months or for the remaining period of the contract, whichever is shorter, otherwise mandated in the contract.
in the unlimited contract, the Employer can terminate the contract after notifying the worker within a month not more than 3 months. If the employer did not complain about the notice then he must pay instead of the notice period and the compensation must be as the worker's wage for that period full of part of it.
Therefore, you should not sign the termination until after receiving your dues or submitting a complaint to the Labor Office
