Bin collectors in Kirklees have voted to go on strike.
The move comes amid claims workers have been subjected to bullying by management and have been refused to take leave.
Unison, the union, says Kirklees Council's 70 waste staff are owed a total of 23 years' leave.
62 votes were received with 85.5% in favour of a walk-out.
Kirklees Council said it would not "tolerate bullying or harassment" and took any allegations "very seriously".
