454 Mass. Reg. 24.15
If an Agency or Work Site Employer or a person acting directly or indirectly in either's interest offers transportation services that Temporary or Part-time Workers may utilize, the Agency or the Work Site Employer or a person acting directly or indirectly in either's interest is prohibited from charging more than the actual cost of each Worker's transportation or 3% of the Worker's daily wages, whichever is less. The transportation charge shall not reduce the Worker's total daily wages below the applicable minimum wage earned for that day. If an Agency or Work Site Employer or a person acting directly or indirectly in either's interest requires the use of transportation services, there shall be no charge or cost to the Job Applicant or Worker. Any Agency that sends a Job Applicant or Worker to a Work Site Employer to work where, in fact, no work exists, shall fully refund any reasonable costs of transportation expended by the Job Applicant or Worker to the Worker within seven calendar days of the date the Job Applicant or Worker was sent to the Work Site.
