Revisiting page 84 of the 2015 US employee handbook: what is/was our classification? what is/was our eligibility for paid time off and paid company holidays?

Have a closer look at page 84, Exhibit G - Paid Time Off of Lionbridge's 2015 US Employee Handbook. Remember that this document was supposedly sent to us on March 9, 2015. We write supposedly because none of the Tier1 employees we interviewed could find this email nor the handbook in their email archives nor did they remember having confirmed they had received it and read it.
Notice the distinction between HP (Hewlett Packard) and Non HP employees. 
If we are to believe the handbook, by that time 'all regular employees are eligible per the chart above'. Does that mean we should have been eligible for paid time off and paid company holidays as soon as March 9 2015 but were just not 'told' by Lionbridge?
Or were we excluded from this because we were are part of a unit that was/is unionized and in the process of collective bargaining? Why was this policy change never mentioned by the Lionbridge's representatives during the collective bargaining meetings?
What is our classification today as Tier1s in this unit? 
What was our classification on March 2015?
