What is the reason why it is difficult for pharmacy promoters to recruit?

In addition to the "low salary and monotonous work" said upstairs, there are also some manufacturers who mislead consumers and ask promoters to deceive customers. Set unrealistic promotion targets. In addition to these reasons, most representatives of pharmaceutical production enterprises are unable to sign labor contracts with promoters, have no basic welfare guarantee (insurance), and their wages are unstable. In addition, promoters themselves always feel that they are not regular employees of pharmacies and have no sense of belonging.
