I'm pretty sure I know this answer but I'll ask anyway - I just reviewed the CBA. When my vacation award overlaps my scheduled pattern is vacation pay (3.65) paid above min guarantee like hostile area pay or is it part of the min guarantee calculation?

IOW if I work 7 days and have 7 vacation days then that's below 62hrs.
4.85 x 7 + 3.65 x 7 = 59.5 so I get paid 62 hrs.
