This is why I will not take a full-time position ATM. The deductions are ridiculous, and the pay difference between a part-time employee and a full-time employee is small enough to make me cringe.
If you have multiple children, and a spouse with no benefits, then it may be worth it for you, even then I find it hard to believe one family uses thousands of dollars worth of benefits per year.
I work 45 hours per pay period. A full-time employee works 75. My net pay is $1109 per pay period, assuming I don't pick up any further shifts. A full-time employee nets about $1450. $350 more per pay period for double the work doesn't seem worth it to me, but it depends on your preferences. Some people like consistency, so a full-time schedule works for them.
You can make a lot more money by taking a part-time position, and just pick up extra shifts.
