well if youre in a major union like 15 or 14 youll be doing a lot of "prevailing wage" work on public works projects (like the new Yankees Stadium)
those locals are in NYC (5 boroughs)

the pay is based on a "schedule"
basically a list of pay broken down by county and actual job classification

of course NYC is the highest paid, almost double compared to a lot of other counties

it covers a lot of jobs
but an example for NYC heavy construction
this is all straight time
a tower crane operator makes $67.83 per hour
a forklift operator makes 47.31
the mechanics are about the same for forklift operators
but at those wages whos gonna complain

not to mention whats known as your "stamp"
thats your benefits, pension, etc
thats usually close to what youre making an hour
benefits are 100% paid except for union dues (which are well worth it)

OT is after 8 hours in a a day not 40 in a week holidays and sundays are OT+ usually

but there is a lot of different schedules and its very tough to read (kinda like stereo instructions lol)

o yeah if you work at night
theres "night differential" which will add 10-20 an hour
