The Pros and Cons of The Gig Economy for Companies

Pros:

• No fixed salary. When you pay employees on a fixed salary, you are required to pay for holidays and sick and vacation pay which can be expensive for a business. If you hire a gig worker on a contract, you only pay them for the time they work.
• Flexible employees. You can build a community of reliable and skilled gig workers so no matter what the job is, or where it is located, you are likely to have it covered by one of your trusted contractors.

Cons. 

• Workers may not be as invested. Because gig workers are not permanent employees, they may not be as loyal to your company and can leave at any time.
• Ethical issues. The gig economy has come into question with fair treatment of freelance workers because they are working without benefits (other than pay). Employers need to be aware of ethical issues that may arise.
