Any temporary residence permit(blue card) issued concerns the permanent residence permit profile and gives the same rights as the permanent residence permit under issuance. If your temporary PR is for employment yes you could work from now but be sure what kind of residence permit you had applied for. For example, the permanent residence permit for property owners does not give access to the labor market, so you cannot work legally in Greece, either as a temporary PR holder or as a Golden Visa beneficiary.
According to the immigration law, the foreigners who applied for the Greek permanent residence cards as owners of a property in Greece, are not entitled to work in Greece. For that reason, the blue card doesn’t allow a foreigner to work as well. If the foreigner applies for a residence card of another type, for instance, employment, then the blue card allows working until the residence card is issued.
As a blue card holder, you are allowed to work in Greece as long it is valid. Further actions would be needed.
