The GMB said its members employed by Imperial Tobacco face an annual bill of GBP288 after the company decided to pass on the cost of the levy, which is being imposed by Nottingham City Council.
Workers will ban overtime from the end of the month and will work to rule for the first week in May.
GMB official Chris Needham said: "The company is adamant it is going to pass on this workplace car parking levy of GBP288 a year to its employees.
If there is to be a workplace car parking levy, the employers should pay it.
"The council say they want to raise GBP14 million a year from this levy, which is a straightforward tax on jobs, whoever pays it."
