In their simplest form, metric-like Lagrangians for higher-spin masslessfields display constrained gauge symmetries, unless auxiliary fields areintroduced or locality is foregone. Specifically, in its standard incarnation,gauge invariance of Maxwell-like Lagrangians relies on parameters withvanishing divergence. We propose an alternative form of the corresponding localsymmetry involving unconstrained parameters of mixed-symmetry type, describedby rectangular two-row Young diagrams and entering high-derivative gaugetransformations. The resulting gauge algebra appears to be reducible and wedisplay the full pattern of gauge-for-gauge parameters, testing its correctnessvia the corresponding counting of degrees of freedom. Incidentally, this showsthat massless higher spins admit a local unconstrained formulation with no needfor auxiliary fields.
