Roughly 37% of the UA Local 537 package is employer-paid benefits and fringes rather than wages, which is why the package figure and a take-home hourly rate are not the same number.
| Benefit & fringe contributions | $39.22/hr | Derived: total package minus base wage. This is the employer's combined hourly contribution to the funds, not take-home pay. |
|---|---|---|
| What the contributions fund | Health & welfare, pension, annuity, training and industry funds | Standard fund categories in mechanical and electrical agreements. The exact split between funds is set in the local's agreement, the hall or fund office publishes the schedule. |
| Paid on | Every hour worked | Fringe contributions are made per hour worked, so they scale with dispatched hours and are paid to the funds rather than to the member. |
