If you get sick there's a chance you get demoted and put back on the casual roster, even if your full-time benefits are still active. If you get hurt working for a different employer your disability coverage does not apply. No real sick days unless you're office staff.
No such thing
None. Your sick days are paid out. If you get sick you might lose your fulltime spot.
Sick time is only for office based staff. Field staff are not entitled to sick time. You don't work, you don't get paid. There is no short term disability. Their long term disability wait period is 6 months.
The policy is quite generous. About two weeks per year.
