The main differences between full-time and part-time jobs are the hours worked, with full-time usually being 40 hours per week over 5 days, while part-time allows more flexibility in choosing hours. A benefit of full-time jobs is receiving overtime pay and benefits like paid time off, while freelancers are not guaranteed steady work or pay when not working. Freelancing makes it difficult to build a regular client base unless exceptional work is consistently delivered, whereas full-time employment provides more job security as long as the company remains in business.
