If I am a full-time employee, can my employer cut my hours legally so I lose my health care benefits, etc?
I am considered a full-time employee in my current position. My employer has threatned to cut 1 shift of mine a week so that I don't make my full-time status and therefore loose my health and dental coverage, as well as my other benefits that come with my full-time status.
Yes, your employer may do this. Employers decide how many hours their workers work; they have the right to reduce an employee's hours, including to the point where he or she loses benefits. The fact that you have been considered a full-time employee in the past does not require your employer to always keep you at full-time hours. The exception would be if you have an employment contract (including a union agreement) which defines your hours or benefits; if you do, it is enforceable.
