The new contract between amalgamated UE Local 155 and materials testing machine company Tinius Olsen includes several measures that give workers greater control over their time.

Vacation time was greatly improved by eliminating the old system of attendance incentive days, personal days, and two holidays, and turning them all into vacation days. The union won more vacation flexibility by getting workers the right to use some vacation in one-hour increments, and reduced the notice time workers are required to give for vacation of three days or more. UE members also won greater rights to carry over vacation days, and the company agreed to look into a digital system to allow workers to check their accumulated time.
