You do know that contractors get paid more than an employee would for the same role, right? Built into that extra cost is the lack of paid holidays, benefits, and the fact that they carry more risk if they are let go because they don't get benefits. An employee will often put in more hours than a standard 40 hour a week for special projects, extra work, etc. etc. without reimbursement. A contractor gets paid for every hour, including time to drive to an airport for work travel, time on the flight, etc. etc. etc. The model is different. You need to educate yourself before making comments about class action, and proving someone is not an employee (this is also extremely easy to do since the two are set up in the system, paid, categorized and identified differently).
Also...MENTAL HEALTH claims from receiving emails for things they don't get????
Don't diminish people who actually struggle with mental health issues by trying to make it a "route" to be litigious. This level of ignorance and entitlement is exactly what k–ls companies.
