Quote from LeeD:
My guess is they are talking of:
1) Qualifications required to perform particular jobs. It's bizzare but to write a High Frequency Trading platform with Direct Market Access you don't need any specific qualifications but to paint someone's house you need to be certified. So do you if you want to do babysitting more than a few hours per week.
2) What needs to be done in order to hire an employee. With a contractor you just need a contract and you pay what's in the contract. With an employee you may need to check their right to work in the country, get their social security number, issue payslips, pay employer's social security withholding tax (which is payed on top of gross salary/wage), deduct employee's personal income tax etc...
