According to the regulations of our province, enterprises involved in employment and poverty alleviation enjoy the following specific preferential policies: ① If public employment service agencies and professional intermediaries hold special job fairs for poor family laborers and other qualified personnel free of charge (the scale of job fairs should reach: more than 40 employers can recruit and provide more than 400 jobs), they will be given a one-time reward subsidy of 8,000 yuan; Every time the employment agency successfully introduces 1 poor family labor force for free (that is, signing a labor contract with the employer and paying social insurance premiums, but excluding public welfare jobs), it will give the employment agency 300 yuan an employment subsidy. ② "4050" people from poor families (i.e. women over 40 years old and men over 50 years old) and disabled people with working ability are included in the scope of public welfare posts, and the subsidy standard for public welfare posts is 700 yuan per month; Public welfare posts developed by governments at all levels in the province are inclined to the above-mentioned personnel under the same conditions. (3) The employing unit that has signed a labor contract with poor family laborers for more than 2 years and paid social insurance premiums will be given a one-time incentive subsidy of 2,000 yuan for each person recruited 1 year after fulfilling the contract. (4) If all kinds of employers (including public welfare posts) recruit "4050" people from poor families and disabled people who have the ability to work, and sign labor contracts with them for more than 1 year and pay various social insurance premiums, they will be given social insurance subsidies. The social insurance subsidy standard is the pension, medical care and unemployment insurance expenses actually paid by the employer for the labor force of poor families who are employed, and the subsidy period shall not exceed 3 years.
