Sometimes that goes afoul when it's ruled that they put requirements that are only valid for employees on contractors.
I don't follow this? Is this predicated on the fact that gig corps can choose not to work with contractors that don't meet their criteria? If so, how is this different from only using lumber yards that consistently meet your expectations?
The implication of the parent poster seems to be that there are legal requirements regarding contractors and legal requirements regarding employees but gig corps would prefer to treat their workers as one or the other class depending on which is to their benefit - which would be against the law because of the aforementioned concept "legal requirements".
- requiring specific dress code is non-enforceable on contractors in many places
- contractor is not required to provide specific person to fulfill the job, only a person of appropriate qualifications (it's valid for there to be a check on those qualifications)
- in UK case, contractor might be asked to prove that they have a substitute to work in their place!
- [Poland, possibly other] having only one client is not illegal, but can be grounds for investigations and if it's your only client where you work for equivalent of full-time job, it will be evidence for tax fraud
- You can not enforce working hours on contractors in most jurisdiction, only specific deliverables (taking part of work meetings is deliverable, requiring availability in general of specific person at specific times can be grounds for reclassification)
- above is often linked with "gig economy" - rules regarding "contractors" needing to pick up available jobs etc. are often considered illegal skirting of employment law.
As sibling comment mentioned, more is available from your local (too) friendly search engine. And employment lawyers and HR specialists.
There is a way of calculating the pay for a job. It is predictable. Publish the algorithm. Want to change it? Great. Update the documentation and then publish that. The workers should be able to calculate exactly what they are owed. They can decide to leave or stay.
Only in America are people deflecting by bringing up the employment status of people when the issue is a lack of transparency designed to allow wage theft.
