The threshold of the cleaning market is low, so many people have a bucket; two people; three or four pieces of cloth, they begin to take care of the children. It is a bit of a mistake and the employer may not find him. Want to find a regular, good cleaning company, it is necessary, and now I suggest some points for the friends of this site reference!
First, we must first look at whether the company is registered and whether it is legal business; (before confirmation, it is required to produce three certificates: business license, safety construction permit, health certificate).
Second, look at the company's establishment period, whether there is skills training, there is no work experience. Some companies have just opened their business, and they just found a few people and they are established. All aspects are immature and there is no practical work experience. As a result, employers have to pay for it.
Third, the quote should be clear; some cleaning company quote is very low, can really get to the house, there will be a lot of things that need to increase the price, when it does not work well, do not do it again. It makes you very unhappy.
Fourth, personal guerrillas (building elevators, small advertising on the door to the door) are best not to find, because individuals generally do not have any security measures, security risks are large. In addition, no one can find the property once the owner’s property is lost. There is no guarantee.
5. If the workers ask too much, the owners need to pay attention to prevent the bad people from calculating.
